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.

*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.
