In order to elucidate the effects of lead and sulfur components on surface durability of case-hardened chromium molybdenum steel SCM415 rollers, case-hardened rollers made of commercial SCM415 steel, special SCM415 steels with 0.056% and 0.169% lead and special SCM415 steel with 0.056% sulfur were fatigue-tested under a rolling with sliding contact condition. The experimental results were discussed by the calculated results about amplitude of ratio of shear stress to hardness. It was clarified that at a higher Hertzian stress range the fatigue life was shortened by addition of lead and sulfur to the steel but that at a lower Hertzian stress range the fatigue life was hardly affected by the addition of them.
