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.
The following datasheet provides an overview of AISI 4023 alloy
steel.
