Introduction
Alloy steels comprise different 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 provides details AISI 8822H alloy steel.
