BLACK SAE 8620

Description

SAE 8620 is a low alloy case hardening steel. After carburizing/carbonitriding and hardening it produces a hard wear resistant case with tough core, with good resistance to shock. The ‘as rolled and quenched’ surface hardness usually ranges from 37-43HRc. This grade demonstrates reasonably high hardenability, and excellent forgeability and it will weld.This material can be used as an alternative to more costly alloyed case hardening steels.
