A Guide to Steel Grades: Low Carbon, High Carbon, and Stainless Steel

High carbon steel

Steel is the backbone of countless industries, from construction and automotive to cookware and medical devices. But not all steel is created equal. The specific properties of steel can vary widely depending on its carbon content and alloying elements. 

At Three D Metals, we offer a range of steel grades tailored to meet the needs of various applications. Let’s dive into the key differences between low carbon, high carbon, and stainless steel.

Low Carbon Steel: Versatile and Highly Formable

Low carbon steel, including grades such as C1006 through C1010, is known for its exceptional formability. Defined as a type of steel alloy that contains less than 0.25% carbon content, this is ideal for applications where parts are not heat-treated, and the strength depends on the initial temper, part geometry, and cold working during forming. 

Special low-carbon grades also offer significantly better deep draw ability compared to regular low-carbon steels, making them a go-to choice for manufacturing processes that require extensive shaping and forming.

Applications:

  • Automotive body panels
  • Pipes and tubes
  • Machinery parts that require bending or deep drawing

High Carbon Steel: Strength and Hardness for Demanding Applications

High carbon steel is designed for applications that require enhanced strength and hardness. These steels are typically intended for heat-treated applications with carbon contents ranging from about 0.35% to 0.95%. 

Adding alloying elements like chrome, nickel, and molybdenum further enhances their hardening and heat-treated properties. While high carbon steel is less formable than low carbon steel, it excels in scenarios where durability and resistance to wear are crucial.

Applications:

  • Cutting tools
  • Springs
  • High-strength wires
  • Parts requiring hardening, such as gears and knives

Stainless Steel: Corrosion Resistance and Cleanability

Stainless steel is celebrated for its corrosion resistance, thanks to the chromium content that forms a protective layer of chromium oxide on the surface. This unique property makes stainless steel the material of choice for environments where cleanliness and resistance to rust are paramount. 

Additionally, stainless steel offers high tensile strength, which can be further enhanced through cold working. Its cleanability and strength make it an ideal material for a wide range of applications, from food processing to aerospace.

Applications:

  • Cookware and cutlery
  • Medical instruments and implants
  • Construction, including bridges and monuments
  • Automotive and aerospace components
