AISI 4820 Alloy Steel (UNS G48200)

AISI 4820 Alloy Steel (UNS G48200) Image

Alloy steels comprise many types of steels whose compositions are more than the limitations of C, Mo, Cr, Va, Mn, Ni, Si, and B which have been allocated for carbon steels. These steels are more responsive to mechanical and heat treatments than carbon steels.

The following datasheet provides more details on AISI 4820 alloy steel.
