Correlation relationships between the fatigue limit and the mechanical properties of 40 and 08Kh18N12T steels under static and dynamic loads are obtained. A nomogram is proposed for approximate determination of the fatigue limit from the results of hardness measurements in relation to service time of 08Kh18N12T steel.
