Abstract In order to improve the contact fatigue life of the bearing steel, the rare earth was used as deoxidizer partly instead of Al in the conventional processing. This RE ladle deoxidizer in amount of 0.08 wt-％ of the melt produces inclusions of Ce_2S_3, CeS, La_2S_3, etc. which tend to increase the fatigue life of the steel by 50％.
