Applications: in the carburized condition this alloy is used for gears, ring gears, shafts and crankshafts.

Introduction:

Principal Design Features: AISI 8620 is a hardenable chromium, molybdenum, nickel low alloy steel often used for carburizing to develop a case-hardened part. This case-hardening will result in good wear characteristics.

Machinability: Machining is done prior to carburizing to within as close a tolerance as possible. Finish machining, after heat treatment and/or carburizing, should be at a minimum so as not to impair the hardened case of the part. Machining may be done by conventional means prior to heat treatment - after carburizing machining is usually limited to grinding.

Forming: Forming characteristics of 8620 alloy are good in the annealed condition.
