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