Heat Treatment:
Forging: 52100 bearing steel is forged at 1950 – 2100ºF (1065 – 1150ºC), and should not be forged below 1700ºF (925ºC.)
A post-forge equalization treatment is recommended at 1375ºF (745ºC) for 4-6 hours followed by air cooling.
Annealing: 52100 bearing steel is annealed at 872°C (1600°F) followed by slowly cooling to reduce cold working or machining stress.
Hardening: 52100 bearing steel is hardened by cold working, or heating and quenching. It can be carburized at 913°C (1675°F)
followed by quenching. It is again heated at 788°C (1450°F) followed by quenching for the second time.
