Carbon Steel Bar

Carbon Steel Bar

The properties of carbon steel are high hardness, strength, wear resistance and anti-corrosion.

Carbon steel is an alloy with carbon and iron, with carbon content up to 2.1% by weight. The increase in the carbon percentage will raise steel’s hardness and strength, but it will be less ductile. Carbon steel has good properties in hardness and strength, and it is less expensive than other steels.
