How to Carburized 8620?

HEAT TREATING
8620 can be hardened to 1500° F followed by water quench. Carburize at 1650° - 1700° F in an appropriate carburizing medium and oil quench to harden. Tempering of carburized parts is done at 250° - 300° F and will result in the alloy having a core strength of approximately 135,000 psi minimum.

How do you anneal 8620 alloy steel?

Annealing. AISI 8620 may be given a full anneal at 1550 F and slow cooling at not more than 50 F per hour down to 850 F. From there it may be air cooled.

Can 8620 be forged?

This alloy is forged at a start temperature of around 2250ºF (1230ºC) and could be forged down to approximately 1700ºF(925ºC.) The alloy is air cooled after forging. The method of forging AISI 8620 steel used is closed die forging, which is very suitable for small precision components.
