Introduction
Alloy steels contain elements such as chromium, cobalt, nickel, etc.
These steels comprise a wide range of steels with compositions that
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. In comparison with carbon
steels, alloy steels are a lot more responsive to mechanical and heat
treatments.
The following datasheet provides an overview of AISI A533 grade
D-PVQ alloy steel.
