Introduction Carbon steels are steels that contain only carbon as their specific alloying element. Traces of 0.4% silicon and 1.2% manganese can be found in these steels. Carbon steels also contain small quantities of residual elements such as copper, nickel, molybdenum, aluminium and chromium. The following datasheet provides an overview of AISI 1026 carbon steel.
