AISI 4147
Alloy steels comprise a wide range of steels having 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 contain elements such as chromium, cobalt, nickel, etc. These steels can be subjected to unique melting and deoxidization processes for specific applications.
