Alloy Steel AISI 6150 Forgings
6150, G61500
Alloy steels are designated by AISI four-digit numbers. They are more susceptible to mechanical and heat treatments than carbon steels. Alloy Steel AISI 6150 comprise different types of steels with compositions which exceed the limitations of B, C, Mn, Mo, Ni, Si, Cr, and Va in the carbon steels.
