Carbon Steel

Carbon steel is a malleable, iron-based metal containing less than 2% carbon (usually less than 1%), small amounts of manganese, and other trace elements. Steels can either be cast to shape or wrought into various mill forms from which finished parts are formed, machined, forged, stamped, or otherwise shaped. Carbon steels are specified by chemical composition, mechanical properties, method of deoxidation, or thermal treatment.
