Bearings are repeatedly subjected to severe compressive and impact load for a long time in its application which warrants a high rolling contact fatigue life. Through hardenable SAE 52100 is extensively used as bearing steel world wide because of its excellent rolling contact fatigue life. Martensitic structure and carbide morphology as well as the retained austenite percentage of SAE 52100 steel are significantly affected by rate of quenching which have direct impact on the dimensional stability of bearing component during application.SAE 52100 when quenched from austenite, does not transform completely to martensite. At room temperature the hardenable microstructure consists of martensite and retained austenite along with undissolved carbide. During application of bearing at high temperature, the retained austenite undergoes martensitic transformation resulting in volume expansion ultimately leading to seizure of bearing. Therefore, it is very much important to control the dimensional stability of bearing components made of SAE 52100 steel. The present paper is an attempt to study the effect of quenching on the dimensional stability of SAE 52100 bearing steel.
