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