Carbon steels are classified based on the amount of carbon content in the steel. The four main classes are mild and low carbon steel, medium carbon steel, high carbon steel, and ultra-high carbon steel.
Carbon steels are steels in which the main alloying additive is carbon. Alloy steels are steels alloyed with other metals or materials in addition to carbon to improve properties.
Mild and low carbon steels contain 0.16–0.29% carbon. They are the most common form of steel as they come at a relatively low cost and provide material properties that are acceptable for many applications. They are neither brittle nor ductile, but are malleable. The surface hardness can be increased through carburizing.
Medium carbon steels contain approximately 0.30–0.59% carbon. They balance ductility and strength and have good wear resistance. They are used in forging and for large industrial and automotive components.
High carbon steels contain approximately 0.6–0.99% carbon. They are very strong and are used for springs and high-strength wires.
Ultra-high carbon steels contain approximately 1–2% carbon. These steels can be tempered to great hardness and are used for specialized products such as knives, axles, or punches. Steels above a carbon content of 1.2% are generally formed through powder metallurgy. Steels with carbon content above 2% are considered to be cast iron.
