    The wide range of available steels can mostly be categorized into one of three families: carbon steels, alloy steels and stainless steels. Carbon steels are body-centered cubic (bcc) in structure. Those containing over about 0.1% C (depending on section thickness) can be hardened by heat treatment. The strength is primarily dependant on …
