Dear sir,
We are one of commercial heattreaters and heattreat bearing
race,both inner and outer.These are made out of AISI 52100
steel.We are facing growth problem during hardening which is
causing dimensional changes of rings.This change in dimensions problem in grinding due to increase in ID and OD.We tried to control this structural phenomina by heattreating at different temp. for no possitive results.
Can you please do suggest with your great experience?

With regards--Prasanna kumar
