Carbon steel is a type of steel where the main alloying element is carbon. It is one of the most widely used materials in construction, manufacturing, and various industries due to its balance of strength, ductility, and affordability. The properties of carbon steel can be adjusted by varying the carbon content, which typically ranges from 0.05% to 2.0% by weight.

  • Low Carbon Steel (Mild Steel):

    • Carbon Content: Up to 0.3%
    • Characteristics: Offers good ductility, weldability, and moderate strength. It is commonly used for structural applications and in the manufacturing of products like sheets, plates, and bars.
  • Medium Carbon Steel:

    • Carbon Content: 0.3% to 0.6%
    • Characteristics: Provides a balance between ductility and strength, making it suitable for automotive and machinery components. It can be heat treated to harden its surface.
  • High Carbon Steel:

    • Carbon Content: 0.6% to 1.4%
    • Characteristics: Known for its high strength and hardness, high carbon steel is often used in tools, springs, and high-wear applications. However, it is less ductile and more challenging to weld.
  • Ultra-High Carbon Steel:

    • Carbon Content: 1.4% to 2.0%
    • Characteristics: This type of carbon steel is extremely hard and strong but very brittle, making it suitable for specialized applications like knives, cutting tools, and certain industrial machinery components.
