SAE 8620 steel

8620 is a low alloy case hardening steel which is supplied to American standards SAE 8620 and AISI 8620. 8620 can be carburised, which will achieve a tough core with a hard wear resistant case. 8620 provides a combination of toughness and wear resistance. 8620 is supplied in either the as rolled or annealed condition for subsequent case hardening.
