Stainless Steel Strip---AISI 1044 Carbon Steel (UNS G10440)
Introduction Carbon steels area unit a class of steel containing zero.12 to twenty carbon. once the share of carbon content will increase, hardness and strength of those steels increase with heat treatment, however lose alittle quantity of their malleability. AISI 1044 steel is medium-carbon steel that may be heat treated, flame or induction hardened. it's counseled that carburizing or cyaniding be avoided. The following sections can discuss AISI 1044 steel in futher detail. The Chemical Composition The chemical composition of AISI 1044 steel is printed within the following table.
