  • S06 steel is a new kind of precipitation-hardened stainless martensite steel. The fatigue properties between 106~109 cycles of S06 steel were tested with ultrasonic fatigue testing machine. Results show that fatigue failure takes place after 107 cycles and an endurance limit does not exist for S06 steel. Fatigue design on infinite life criterion can-t be used for components made of this steel. High-cycle fatigue testing method with the same loading mode and approximate specimen dimension with that of ultrasonic fatigue tests was used to study the fatigue properties between 104~107 cycles. The results show that fatigue strength of S06 steel is higher with ultrasonic fatigue testing method. Ultrasonic fatigue testing data was amended by comparing the fatigue strength coefficient of Basquin formula. The P-S-N curves at 106~109 cycles of S06 steel considering cracking initiation mechanism and frequency effect were fit with linear variance regression analysis method and the curves can be used for fatigue design of engineering components with long lifetime.
