Steels with only carbon as their specific alloying element are known as carbon steels. Traces of 0.4% silicon and 1.2% manganese can be found in these steels. Carbon steels also contain small quantities of copper, nickel, molybdenum, aluminium and chromium.

The following datasheet provides an overview of AISI 1015 carbon steel.
