Heat Treatment:
SAE 52100 alloy bearing steel is heated at 816°C followed by quenching in oil. Before performing this process, it is subjected to normalizing heat treatment at 872°C followed by slowly cooling in order to reduce the machining stress.
Hardening:
SAE 52100 alloy 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.
Tempering:
Temper to desired hardness as indicated by tempering curves after water or oil quench.

Forging Properties:
AISI 52100 alloy steel is forged at 927 to 1205°C, and should not be forged below 925ºC. A post-forge equalization treatment is recommended at 745ºC for 4-6 hours followed by air cooling for SAE/AISI 52100 steel.
Stress Relieving:
Heat it up to 600-700℃, stay the temperature, furnace cooling. The need for the hardness of mold steel is 187-229HBS. The characters remove the work hardening and residual stress.
Normalizing:
Heat it until the temperature at the range of 930-950℃, maintain the temperature, air cooling. The hardness needs to be 302-388HBS.
Annealing:
AISI 52100 alloy steel is annealed at 872°C (1600°F) followed by slowly cooling to reduce cold working or machining stress
