A quantitative prediction method for notch effect in fatigue limit reliability of high strength steels with defects or non-metallic inclusions is proposed with a stress concentration and scatter of Vickers hardness and defect size distribution. Especially in this report, the method can be used for a structure with a deep notch under zero mean stress. And fatigue tests of notched specimens are carried out on quenched-tempered 0.5% carbon steels: whose average Vickers hardness is about 600. Comparing a predicted fatigue limit distribution with experimental data, the applicability of the present method is examined and confirmed.
