AISI 4620 Alloy Steel (UNS G46200)

AISI 4620 Alloy Steel (UNS G46200) Image

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

The following datasheet provides an overview of AISI 4620 alloy steel, which has good strength and toughness. AISI 4620 alloy steel can be heat treated to obtain high strength.
