Introduction
Alloy steels contain elements such as chromium, cobalt, nickel etc.
In comparison with carbon steels, alloy steels are a lot more
responsive to mechanical and heat treatments.
Alloy steels comprise a wide range of steels whose compositions
exceed the limitations of Si, Va, Cr, Ni, Mo, Mn, B and C allocated for
carbon steels. Alloy steels can be subjected to unique melting and
deoxidization processes for specific kind of applications.
The following datasheet provides an overview of AISI 4617 alloy
steel.
