1. Carbon steel is categorized by the amount of carbon in the alloy, which impacts the properties of the steel. Low carbon steel, with 0.05-0.3% carbon, is ductile and malleable. It has low tensile strength and can be hardened through carbonizing. It is the least expense of the carbon steel alloys.

Medium carbon steel has 0.3-0.59% carbon, which provides the alloy with increased strength and good ware resistance. It is easy to machine and is used for forged and automotive parts.

High carbon steel and ultra-high carbon steel is very strong and is used for springs and high-strength products. These alloys can be tempered to very high hardness without brittleness, and are used for very high wear applications. These alloys have carbon from 0.6-0.99% for high carbon steel and 1.0-2.0% for ultra-high carbon steel.
