Many kinds of high strength steels have been developed and applied to mechanical structures in the variety of industries. If the static strength level is increased, fatigue strength of the material tends to increase. But, the extent of the increase of the fatigue strength depends on the static strength level and the kind of the material. It is usually expected that the notch effect of the fatigue strength becomes sensitive with increase of the static strength. In this study, such a notch effect of high carbon chromium bearing steel was experimentally examined by performing fatigue tests for notched specimens having different stress concentration factors. Thus it was found that the notch effect of this steel is not so sensitive comparing with the usual steels such as carbon steels.
