Carbon Steel

Affiliated Steel & Tube offers only the highest quality carbon steel products from top mills in the country as well as international suppliers.

What is Carbon Steel?

Carbon steel, also known as plain carbon steel, is a metal alloy; a combination of two elements, iron and carbon, where other elements are present in quantities too small to affect the properties. The only other alloying elements allowed in plain-carbon steel are manganese (1.65% max), silicon (0.60% max), and copper (0.60% max).

Steel with a low carbon content has the same properties as iron, soft but easily formed. As carbon content rises, the metal becomes harder and stronger but less ductile and more difficult to weld. Higher carbon content lowers steel's melting point and its temperature resistance in general.

Types of Carbon Steel

  • Mild (low carbon) steel: approximately 0.05–0.15% carbon content for low carbon steel and 0.16-0.29% carbon content for mild steel (AISI 1018 steel). Mild steel has a relatively low tensile strength, but it is cheap and malleable; surface hardness can be increased through carburizing.
  • Medium carbon steel: approximately 0.30–0.59% carbon content (AISI 1040 steel). Balances ductility and strength and has good wear resistance; used for large parts, forging and automotive components.
  • High carbon steel: approximately 0.6–0.99% carbon content. A very strong carbon alloy is used for springs and high-strength wires.
  • Ultra-high carbon steel: approximately 1.0–2.0% carbon content. Steels that can be tempered to great hardness. Used for the manufacturing of knives, axles or punches. NOTE: Most steels with more than 1.2% carbon content are made using powder metallurgy and typically fall in the category of high alloy carbon steels.
