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