Steel is one of the most versatile and widely used materials in the modern world. It’s made primarily from iron, with a controlled amount of carbon and other alloying elements. As we discussed in a previous blog, steel differs from wrought iron and cast iron due to its lower carbon content and greater strength and flexibility.
Today, there are thousands of steel grades and formulations, each made for specific performance requirements across the construction, transportation, mining, and manufacturing fields.
Conveniently, these types can be grouped into four general classes of steels that we will explore below.
Understanding the Main Types of Steel
Each steel category is formulated with unique properties that make it ideal for specific applications. Here is a detailed breakdown of the most common types of steel and how they differ from one another.
Carbon Steels
The most widely produced category, carbon steels represent about 80 to 90% of global steel production. They usually contain less than 1% carbon and are softer and easier to form than other classes of steel. Depending on their carbon content, they may also be classified as:
- Low-carbon steel, (mild steel): Ductile and easy to weld. It is commonly used in automotive panels, construction materials, and consumer goods.
- High-carbon steel (cast iron): Harder and more brittle. It is usually found in cutting tools, springs, and high-strength wires.
Carbon steel is used in many everyday products such as car bodies, ship hulls, steel cans, and more but they don’t offer the strength and wear resistance of more advanced steel types
Alloy Steels
Alloy steels are made by adding elements like chromium, manganese, molybdenum, nickel, or vanadium to improve performance. They’re formulated for application requiring enhanced toughness, hardness, or resistance to wear and corrosion.
They are often used in:
- Shot blast cabinets
- Mining screens and grizzlies
- Truck box liners
- Heavy-duty structural components
Many alloy steels undergo heat treatment, quenching, and tempering to improve wear, impact resistance, gouging and tearing.
Tool Steels
Tool steels are specially formulated for high-performance machining, cutting, punching, and forming applications. They’re made from iron and carbon with added alloys such as nickel, molybdenum or tungsten to improve hardness and heat resistance.
Many tool steels, such as Titus Steel’s Toolox 44 steel is a perfect example. It offers excellent machinability despite a hardness of 45 HRC and is ideal for:
- Plastic molds
- Guide rails
- Bending and forming tools
Tool steels are essential in manufacturing dies, precision machine parts, and industrial molds.
Stainless Steels
The most familiar steel to most people is stainless steel, as it’s used to make many everyday items such as kitchenware, architectural finishes, and medical equipment. In addition to iron and carbon, it contains a high proportion of chromium (usually at least 10.5%) and often nickel, which react with oxygen to form a passive layer of chromium oxide on the surface, which protects the steel underneath from rust.
Stainless steels are not typically chosen for applications requiring extreme wear resistance but they excel in environments where hygiene and corrosion resistance are of utmost importance.
Wear Resistant Steels
The Ultimate in Durability
When performance under extreme abrasion or impact is the top priority, wear resistance steels are the best solution. Titus Steel offers advanced wear resistant steels such as ENDURA, ENDURA Dual, and Titus Manganese steel, which are engineered to outlast and outperform standard steels in the harshest environments.
What sets these wear-resistant steels apart?
- Patented alloy formulations
- Superior work-hardening capabilities
- Outstanding resistance to gouging, cracking, and deformation
- Long service life, reducing replacement cycles and maintenance costs
These wear resistant steels are best for mining, construction, material handling, and other heavy-duty applications where surface wear in a major concern.
Frequently Asked Questions About Steel Types
What is the difference between alloy steel and carbon steel?
Alloy steel contains chromium and nickel to enhance specific properties, while carbon steel primarily relies on carbon content and is more basic in composition.
Is stainless steel a type of alloy steel?
Yes, stainless steel is technically a corrosion-resistant alloy steel with high chromium content. It’s classified separately because of its unique properties and uses.
What is wear resistant steel used for?
Wear resistant steel in used for mining equipment, excavator buckets, screens, and truck beds.
Can Toolox 44 be machined easily?
Yes. Despite its high hardness, Toolox 44 has excellent machinability, making it suitable for precision tools and mold manufacturing.
