Alloy steels contain elements such as chromium, cobalt, nickel. They comprise a variety of steels with compositions that exceed the limitations of Si, Va, Cr, Ni, Mo, Mn, B and C allocated for carbon steels.
When compared to carbon steels, alloy steels are a lot more responsive to mechanical and heat treatments. Alloy steels are used in specific melting and deoxidization processes for particular kind of applications.
