Introduction
Alloy steels comprise many types of steels whose compositions exceed
the limitations of C, Mo, Cr, Va, Mn, Ni, Si, and B allocated for
carbon steels. These steels are more responsive to mechanical and heat
treatments than carbon steels.
The following datasheet will provide details about AISI 8822 alloy
steel.
