Alloy steels are designated by AISI four-digit numbers. They are more responsive to mechanical and heat treatments than carbon steels. They 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.
AISI 4130 alloy steel is a low alloy medium carbon steel, commonly referred to as Chromoly steel or chrome moly steel.
