AISI 4145 Alloy Steel (UNS G41450)

AISI 4145 Alloy Steel (UNS G41450) Image

Alloy steels are steels containing elements such as chromium, cobalt, nickel, etc. 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 can be subjected to unique melting and deoxidization processes for specific kind of applications.

The following datasheet provides an overview of AISI 4145 alloy steel.
