Applications:
Alloy steels contain a wide range of steels whose compositions exceed the limitations of C, Mo, Cr, Va, Mn, Ni, Si, and B fixed for carbon steels. These steels are more responsive to mechanical and heat treatments than carbon steels.
AISI 8620 alloy steel is a common, carburizing alloy steel. This alloy steel is flexible during hardening treatments, thus enabling improvement of case/core properties.
