Heat Treatment for ASTM 52100 Bearing Steel.

ASTM/AISI 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.
Hot Working
AISI 52100 bearing steels alloy can be hot worked at 205 to 538°C.
Cold Working
AISI 52100 bearing steel can be cold worked using conventional techniques in the annealed or normalized conditions.
Annealing
For spheroidize anneale, the following isothermal anneal is recommended:
* 1500ºF (815ºC) for 3 hours
* 1350ºF (735ºC) for 4 hours
* 1250ºF (675ºC) for 3 hours
* Slow cool to 1000ºF (540ºC) then air cool.
Quenching
AISI 52100 alloy bearing steel could be hardened by quenching in water from 801-829 degree or quench in oil from 816-842 degree.
Tempering
Temper to desired hardness as indicated by tempering curves after water or oil quench.
