AISI 4330

Alloy steels contain a wide range of steels comprising compositions that exceed the limitations of Si, Va, Cr, Ni, Mo, Mn, B and C which have been allocated for carbon steels. Alloy steels can be used in unique melting and deoxidization processes for specific kind of applications. Alloy steels comprise elements such as chromium, cobalt, nickel etc, that are not found in carbon steels. In comparison with carbon steels, alloy steels are a lot more responsive to mechanical and heat treatments.
