Abstract An aspect of the intermal fatigue limit for metals was proposed with the aid ofappraisal of the fatigue behaviour of shot peened, nitrided or carbonitrided steels. The inter-nal fatigue limit of metals seems to be 1.35 times of surface one. Based on this aspect, the fa-tigue strength of surface hardened steels was analysed.
