Carbon steels are steels that contain only carbon as their chief alloying element. Traces of 0.4% silicon and 1.2% manganese are present in these steels. Small quantities of copper, nickel, molybdenum, aluminium and chromium can also be found in the carbon steels. AISI 1012 carbon steel is characterized with good machinability and formability, and can be hardened by cyaniding.
