Steel is often perceived as a basic blend of iron and carbon, yet its complexity extends far beyond this common misconception. Contrary to popular belief, more than 3,500 distinct grades of steel exist. The variety in steel grades comes from the different amounts of carbon, the addition of other alloying elements, and the various ways manufacturers make them.

4 Types Of Steel

Experts categorize steel into four primary groups — Carbon, Alloy, Stainless, and Tool. Each type has a unique composition and set of applications. So, what exactly are these different types of steel made of, and what purposes do they serve?

1. Carbon Steels

Carbon steels are primarily iron and carbon, with only minimal amounts of other elements. This category is the most prevalent among the four types of steel, making up about 90% of all steel production.

There are three subcategories of Carbon Steel, distinguished by the amount of carbon present in the alloy:

• Low-Carbon Steels/Mild Steels: This subgroup contains up to 0.3% carbon. Due to their ease of shaping and welding, mild steels are commonly used in applications such as construction beams, automotive panels, and furniture.

• Medium Carbon Steels: With a carbon content ranging from 0.3% to 0.6%, medium carbon steels offer increased strength compared to mild steels. They are often utilized in structural components, gears, axles, and shafts.

• High Carbon Steels: These contain more than 0.6% carbon, providing exceptional hardness and wear resistance. They are commonly used in cutting tools, knives, springs, and wire products where hardness and durability are critical. Due to their cost-effectiveness and sufficient strength for major construction projects, companies produce these steels in large volumes.

2. Alloy Steels

Alloy steels are formed by introducing extra alloying elements such as nickel, copper, chromium, and/or aluminum into the steel composition. This improves the steel’s properties including strength, ductility, resistance to corrosion, and ease of machining.

Here’s how different alloying elements contribute to enhancing steel properties:

• Chromium: Enhances toughness and resistance to wear and tear.
• Silicon: Improves magnetic properties, beneficial for generators, motors, and transformers. It also acts as a deoxidizer, reducing defects.
• Nickel: Boosts strength, toughness, and corrosion resistance.
• Aluminum: Lightweight and heat-resistant, ideal for hot exhaust systems and generators.
• Cobalt: Increases heat resistance, suitable for high-speed power tools, and improves cutting capabilities.
• Vanadium: Enhances strength, toughness, and wear resistance, particularly useful in high-power tools.
• Manganese: Creates impact-resistant steel with increased strength and hardenability, utilized in structural applications, safes, and security materials.
• Molybdenum: Strengthens steel at high temperatures and improves corrosion resistance, commonly found in high-pressure industries like underwater, oil, and gas.
• Copper: Offers electrical conduction properties, frequently used in electrical applications.

3. Stainless Steels

Stainless steels comprise 10-20% chromium as their primary alloying element and additional elements like nickel, silicon, manganese, and carbon.

These steels exhibit exceptional corrosion resistance, which makes them ideal for outdoor construction where they can withstand harsh weather conditions. Moreover, they are extensively employed in electrical equipment. For instance, 304 Stainless Steel can endure environmental factors while safeguarding electrical components.

Stainless steel is also predominantly favored across industries for its hygienic properties. It is commonly used in medical instruments, piping systems, cutting implements, and food processing machinery.

4. Tool Steels

As the name suggests, tool steels are highly proficient in cutting and drilling applications. Their exceptional performance is attributed to the presence of tungsten, molybdenum, cobalt, and vanadium, which enhance their resistance to heat and overall durability. 

Due to their ability to maintain shape even under intense usage, they are the preferred material for a wide range of hand tools. They’re commonly used to manufacture drill bits, saw blades, cutters, dies, and punches.

What are the Different Grades of Steel?

Steel grading systems are crucial in categorizing steel types based on their unique properties and applications. These systems provide a standardized way to differentiate between steel grades, ensuring quality and consistency across industries.

For example, cooling heated steel can significantly impact its molecular strength. The time the material is exposed to critical temperature during cooling is also very important. Specific heat-treatment processes can result in different grades, even for steel sheets with identical alloy content.

The ASTM Grading System

The American Society for Testing and Materials (ASTM) utilizes a comprehensive grading system to classify metals. Each metal is assigned a letter prefix denoting its overall category, with “A” representing iron and steel materials. Furthermore, a sequentially assigned number corresponds to the metal’s specific properties, providing a standardized method for classification.

Example:

Consider ASTM A36 steel, a commonly used structural steel in construction projects. In this designation:

• “A” signifies iron and steel materials.
• “36” denotes the minimum yield strength of the steel, measured in kilopounds per square inch (ksi). In the case of ASTM A36, the minimum yield strength is 36 ksi.

The SAE Grading System

The Society of Automotive Engineers (SAE) employs a four-digit numerical system for classifying steel. The first two digits indicate the type of steel and the concentration of alloying elements present, while the last two digits represent the metal’s carbon concentration. This system facilitates precise identification and categorizing of steel grades based on their composition.

Example:

Let’s consider the classification “SAE 1040 steel”:

• The first two digits, “10,” indicate the steel type and the concentration of alloying elements present. In this case, the steel belongs to the 10xx series, which typically denotes plain carbon steel.
• The last two digits, “40,” represent the metal’s carbon concentration. In SAE 1040 steel, the carbon concentration is approximately 0.40%.

Steel grading standards are essential for scientists, engineers, architects, and government agencies involved in material selection and construction projects. By showing the properties of steel, these standards ensure consistency and quality in manufacturing processes.

Is carbon steel superior to mild steel? It’s a trick question since mild steel falls under the carbon steel category.

Carbon is a fundamental element found in all steel varieties. The resulting alloy is classified as carbon steel when carbon is the primary alloying element. Mild steel is also known as “low-carbon” steel due to its lower carbon content. There are various carbon steels, each with different levels of carbon. The suitability of one over the other largely depends on the specific use or application the steel is intended for.

Types of Carbon Steel

Carbon steel, the most commonly utilized material in engineering, makes up about 85% of the global annual steel production. Its carbon content ranges from 0.25% to 2.0% carbon. This broad spectrum offers varied properties, from increased hardness and strength to improved wear resistance, making it suitable for various demanding applications. The classification into low, medium, and high carbon steel further tailors its uses to specific needs. 

• Mild Steel or Low Carbon Steel: Mild steel is characterized by its notably low carbon content, typically less than 0.25%. This minimal carbon composition renders it more malleable and ductile than higher carbon steels, making it exceptionally easy to weld, cut, and form. This affordability, weldability, and versatility make mild steel a staple in various industries and applications.

*Mild Steel vs. High Carbon Steel Comparison Table

Manufacturing Process of Carbon Steel

The manufacturing process involves several intricate stages, each crucial in determining the final product’s properties and quality.

Primary Processes

Through the BOF process, steel can be produced using entirely recycled materials or a blend of recycled and virgin steel.

• Basic Oxygen Furnace (BOF): The primary method for producing mild and carbon steel involves transforming raw materials like iron ore and coke into liquid steel. The process begins with charging the furnace with scrap metal, iron ore, and fluxes. Oxygen is then blown into the furnace at supersonic speeds, which oxidizes impurities like carbon, silicon, and phosphorus. The heat from the oxidation reactions further melts the iron ore, resulting in liquid steel. The liquid steel is then cast into molds to form slabs or ingots, ready for further processing.

Secondary Processes

Market demands for higher-quality steel products have spurred the development of secondary steelmaking processes, allowing manufacturers to tailor the steel composition to produce low carbon steel, medium carbon steel, or high carbon steel.

• Electric Arc Furnace (EAF): In this process, the steel composition is altered by adding or removing specific components or manipulating the temperature. 

EAF processes include:

• Stirring: Separating non-metallic impurities to ensure the steel’s homogeneous combination and composition.
• Ladle furnace: Enables precise temperature control and the measured injection of alloy components.
• Ladle injection: Inert gas is injected into the bottom of the steel bath to achieve a stirring effect.
• Degassing: Removes hydrogen, oxygen, and nitrogen while lowering the product’s sulfur content.
• Composition adjustment: Crucial for achieving stirring, often done through sealed argon bubbling with oxygen blowing (CAS-OB).

• Deoxidizing Steel: Eliminating oxygen is vital in secondary steelmaking. As molten steel solidifies, oxygen reacts with carbon, producing carbon monoxide gas. Controlling deoxidation can alter the material properties of the final product, affecting its suitability for various applications. 

Deoxidizing steel processes include:

• Rimming steels: Non-deoxidized or partially deoxidized steels.
• Capped steels: Similar to rimming, but the mold is capped to prevent the creation of carbon monoxide.
• Semi-killed steels: Partially deoxidized with a carbon content of 0.15–0.3%.
• Killed steels: Totally deoxidized until no carbon monoxide is produced during solidification.

• Casting: Traditional casting methods involve pouring molten steel into individual molds on rail cars. Continuous casting, however, allows molten steel to be cast into shapes more suitable for downstream processing using casting machines. Ingots are then moved to soaking pits to be reheated for hot rolling. A continuous casting machine produces steel into slabs, blooms, or billets.

Finishing Processes

• Rolling: Rolling is critical in shaping steel into its final form. Hot rolling involves heating the steel above its recrystallization temperature and passing it through a series of rollers to achieve the desired shape and dimensions. On the other hand, cold rolling occurs at room temperature and is used further to refine the steel’s surface finish and mechanical properties.

• Heat Treatment: Heat treatment processes like normalizing, annealing, and quenching modify the steel’s microstructure and mechanical properties. Normalizing involves heating the steel to a specific temperature and cooling it in air, improving grain structure and mechanical properties. Annealing involves heating the steel to a specific temperature and then slowly cooling it to relieve internal stresses and improve ductility. Quenching involves rapidly cooling the steel in a quenching medium to achieve high hardness and strength.

• Surface Treatment: Surface treatments like hot dip and electrolytic galvanizing are applied to steel to improve its corrosion resistance and appearance. Hot dip galvanizing involves immersing the steel in a bath of molten zinc, while electrolytic galvanizing involves applying a zinc coating using an electric current. These treatments provide long-lasting protection against corrosion and enhance the steel’s aesthetic appeal.

• Downstream Secondary Processing: Downstream companies further process steel raw materials into finished products through various procedures, such as machining and welding. These processes add value to the steel products and tailor them to specific applications and industries.

Factors to Consider When Choosing the Right Type of Carbon Steel

When selecting the right type of carbon steel for your project, you must weigh various factors to ensure the material meets your needs. 

Here’s what to consider:

Project Requirements

Evaluate the specific strength, durability, and flexibility required for your project. High carbon steel’s resilience is valuable for high-stress environments, whereas mild steel’s versatility may be preferable for less demanding applications. For example, high carbon steel is the best choice for projects requiring a heavy-duty industrial platform under harsh environments due to its unmatched strength and resilience. Conversely, mild steel offers the ideal blend of malleability and structural integrity when crafting lightweight artistic installations.

Corrosion Environment

Consider the corrosion resistance needed for your project. Mild steel often requires additional measures to prevent rust, while high carbon steel, especially high-carbon varieties, naturally offers better resistance. For instance, when crafting a garden trellis or outdoor furniture exposed to rain and humidity, high carbon steel proves resilient against corrosion without extra treatment. Conversely, mild steel may need protective coatings to withstand outdoor conditions.

Cost Efficiency

When deciding between high carbon steel and mild steel, assessing the project’s long-term value and performance requirements ensures you make the optimal investment. Mild steel often provides a more budget-friendly option, offering savings for various projects. This affordability can benefit you as you work on home renovations, build garden structures, or fabricate furniture.

Quick Guide to Metal Melting Points

Metals are found in many items that we see and use every day. Each metal has a different temperature at which it melts, known as its melting point. 

This melting point is important because it tells us at what temperature a metal changes from solid to liquid. This information helps people in various industries, like manufacturing and engineering, choose the right metal for their needs. Below is a table that shows the melting points of some common metals and their common uses.

Factors Influencing Metal Melting Points

Understanding why different metals melt at different temperatures helps us make better choices when using these materials. Several key factors affect the melting points of metals, making each metal unique.

Atomic Structure

How atoms are arranged in a metal plays a big role in determining its melting point. Metals are atoms held together by bonds formed through shared electrons. If these bonds are strong, the metal will have a high melting point because it takes more heat to break them. For example, metals like tungsten have very strong bonds between their atoms and have high melting points.

Atomic Size and Lattice Structure

The size of the atoms in a metal and how they are arranged (lattice structure) also influence its melting point. Larger atoms and more complex lattice structures can lead to higher melting points because they can create stronger metallic bonds.

Bond Strength

Another crucial factor is the strength of the bonds between atoms in a metal. This bond strength depends on how many electrons are involved in the bonding process and how closely packed the atoms are in the metal. Stronger bonds mean a higher melting point because more energy is needed to break these bonds and turn the metal into a liquid.

Electron Configuration

The arrangement of electrons around an atom affects how atoms bond and, consequently, the metal’s melting point. Metals with more delocalized electrons (free to move around) tend to have higher melting points. These free-moving electrons can form stronger bonds in the metal’s structure.

Impurities and Alloying

Adding other elements to a metal (alloying) or the presence of impurities can change its melting point. Impurities can disrupt the metal’s structure, lowering its melting point. On the other hand, alloying can increase the melting point if the added elements form stronger bonds within the metal.

Why Do Metal Melting Points Change Under Different Conditions?

The melting point of a metal tells us the temperature at which it changes from a solid to a liquid. While this temperature stays the same under normal conditions, certain factors can cause it to change.

Form of the Metal

The shape and size of metal pieces can also affect their melting points. When metals are in the form of powders or very thin films, like nanoparticles, they tend to melt at lower temperatures. This is because smaller pieces of metal have more surface area than their volume, making it easier for them to absorb heat and melt.

Temperature Uniformity

Temperature consistency across a piece of metal can affect its observed melting point. In large metal objects, if one part is heated more than another, it might start melting at a lower temperature than expected. This uneven heating can cause variations in the melting point measurements.

Atmospheric Conditions

The environment in which a metal is heated can alter its melting point. For instance, in an atmosphere with reactive gasses, a metal might form compounds on its surface that melt at different temperatures than the pure metal. The presence of oxygen, for example, can lead to oxidation, affecting the melting behavior of the metal.

Thermal History

The history of a metal’s heating and cooling cycles can influence its melting point. Repeated heating and cooling can change the metal’s microstructure, potentially leading to a variation in its melting point over time.

Precision and accuracy are paramount in metalworking. Whether fabricating automotive parts, constructing industrial machinery, or crafting delicate art pieces, understanding the nuances of sheet metal gauge is essential. Sheet metal gauge serves as a universal language, guiding engineers, artisans, and manufacturers in selecting the appropriate thickness for their projects.

What Do Sheet Metal Gauges Mean? 

Sheet metal gauge refers to a standardized method used to measure and categorize the thickness of sheet metal. This system, which has its roots in the British iron wire industry in the 19th century, provides a series of numerical gauge values to represent different thicknesses. Interestingly, as the gauge number increases, the material thickness decreases for most metals, a counterintuitive aspect that often surprises newcomers.

Gauge charts are crucial because they guide the selection process, ensuring that the material chosen meets a project’s structural and aesthetic needs. Whether you’re constructing a robust architectural framework or crafting delicate jewelry, understanding gauge numbers can significantly impact the outcome of your work.

Importance of Understanding Metal Sheet Gauge

Understanding sheet metal gauge, or thickness, is crucial before purchasing. Here’s why:

Durability

The gauge of metal significantly influences the durability of your project or design. Thicker metal can withstand more wear and tear, making it essential for longevity and resilience applications.

Cost Efficiency

Choosing the right thickness is also a matter of cost. Opting for metal that’s too thick for your needs can unnecessarily increase your expenses, affecting production and shipping costs. Conversely, using metal that is too thin might reduce initial costs but could lead to higher expenses due to repairs or replacements.

Structural Integrity

The integrity of any structure or item made from metal heavily depends on choosing the appropriate thickness. Metal that’s too thin may not support the intended load, leading to structural failures or bending under pressure. Ensuring you have the right gauge for your application is pivotal to avoiding such issues.

How Do Sheet Metal Gauges Work?

Unlike standard or metric measurements, which rely on units like inches or millimeters, gauging follows its own set of rules. To find out the actual thickness of sheet metal, you can refer to a gauge conversion chart. This chart helps translate gauge numbers, such as 18 gauge, into familiar measurements—0.0478 inches or 1.214 millimeters for steel, for example. However, the gauge number, like “18” in this case, doesn’t directly relate to the actual thickness measurements.

It’s important to note that various gauge systems are in use today and differ based on the type of metal. For instance, while 18 gauge steel is 0.0478 inches thick according to one system, 18 gauge aluminum might be slightly thinner at 0.0403 inches. This difference underscores the importance of using a gauge chart to accurately determine the necessary thickness for your metal, ensuring that it meets the specific requirements of your project.

Where Did Sheet Metal Gauges Originate?

The history of sheet metal gauges can be traced back to the wire drawing industry before the industrial revolution. Initially, wire was sold by weight, which led to inconsistencies as wires of varying thicknesses could have the same weight. To address this issue, wire drawers began quoting wire based on the number of draws required to create it, with the number of draws becoming the gauge.

This measurement method evolved from drawing wires through progressively thinner dies, assigning each size a numerical gauge. When steelmakers began rolling sheets of steel, they adopted a similar approach. Since measuring sheet thickness directly was challenging, they used the gauge system to specify sheet metal thickness by weight per square foot.

Mild steel, with its low carbon content, is a cornerstone material in engineering and manufacturing, offering a blend of malleability and strength. This overview explores its properties, production, and diverse applications, from construction to specialized industries, highlighting its indispensable role in shaping modern infrastructure and industrial practices.

What is Mild Steel?

Mild steel, also known as low carbon steel, contains a modest amount of carbon, typically ranging from 0.05% to 0.25% by weight. This contrasts with higher carbon steels, which have a 0.25% to 1.25% carbon content. Beyond this carbon threshold, the material would be considered cast iron.

Distinguished by its simplicity, mild steel lacks significant elements like chromium or molybdenum found in alloy steels, granting it distinctive properties that set it apart from its higher carbon and alloy steel counterparts.

The reduced carbon content renders mild steel more pliable, accessible to machines, and better suited for welding than steels with higher carbon content. However, this characteristic limits its hardening and strengthening ability through traditional heating and quenching methods. Mild steel’s simplicity in composition means it possesses less tensile strength due to fewer carbon and alloying elements to obstruct dislocations within its crystal lattice. Yet, it contains a high level of iron and ferrite, attributed to its magnetic properties.

Unlike stainless steel, mild steel’s scarcity of alloying elements leaves it vulnerable to oxidation (rust) if not adequately protected. However, this lack of complex alloying elements makes mild steel more cost-effective than other steels. Its appeal lies in its affordability, excellent weldability, and machinability, making it a highly sought-after material choice for various applications.

How is Mild Steel Made?

Step 1: Extraction of Raw Materials

Mild steel begins with extracting its fundamental ingredients: iron ore and coal. These materials provide the iron and carbon needed to forge steel.

Step 2: The Blast Furnace

The extracted materials are then transported to a blast furnace and heated to extreme temperatures. Iron ore reacts with coal, producing molten iron and releasing impurities.

Step 3: Refining

Molten iron is still mild steel; it contains too many impurities and the wrong carbon content. The iron is transferred to a secondary furnace for refining to rectify this. Through oxidation and adding scrap steel, impurities are reduced, and carbon content is adjusted.

Step 4: Shaping

Once refined, the steel is cast into slabs and subjected to either hot rolling or cold drawing, depending on the desired final product. Hot rolling is performed at high temperatures to achieve larger shapes like beams, while cold drawing focuses on smaller, more precise forms with a finer finish.

Common Uses of Mild Steel in Modern Industries

Mild steel, known for its versatility and affordability, has found its way into many applications beyond conventional construction and manufacturing sectors. Its unique combination of ductility, weldability, and strength makes it an ideal choice for a range of specialized uses that capitalize on these properties. 

1. Dairy Equipment

Mild steel is crucial in the dairy industry and is known for its ease of cleaning and exceptional corrosion resistance. It forms the backbone of dairy processing equipment, vital in maintaining product hygiene and quality throughout the production and distribution chain. This material is especially favored for constructing milk tanks and road tankers, where its ability to keep dairy products cool ensures freshness from farm to processing facility. 

Mild steel’s adaptability is also evident in its use for vats and churns, essential for pasteurizing milk and producing dairy staples like cheeses and butter. Furthermore, its role extends to storage and maturation tanks, where the controlled environment is critical for the aging process of cheeses and the storage of products such as ice cream and yogurt, preventing contamination and preserving quality until they reach consumers. The widespread use of mild steel in dairy processing—from ensuring the durability of transportation containers to facilitating the precise conditions needed for product maturation—underscores its unparalleled capacity to uphold the hygienic integrity and quality of dairy products, demonstrating its indispensable role in the industry.

2. Oil Refinery Equipment

Oil refineries’ harsh, challenging conditions require materials that can handle exposure to highly corrosive substances and fluctuating temperatures. Mild steel’s robustness is tested in this environment, proving its worth in constructing pipes, tanks, and structural supports. Its durability ensures that refinery operations can continue safely and effectively, minimizing the risk of equipment failure.

3. Architectural Trim

Beyond its industrial applications, mild steel is used in the aesthetic aspects of building design. Its malleability allows architects and designers to create decorative and structural elements with intricate shapes, adding a unique visual appeal to buildings without sacrificing structural integrity. From ornamental facades to supportive beams that blend seamlessly with a space’s artistic vision, mild steel offers both beauty and strength.

4. Moderately Stressed Structural Components
