A comparative study of fatigue strength of the industrial alloy Kh15N70V7M3T2YuR was conducted on speciments with electrochemical and mechanical polishing under temperatures of 500, 700, 800, and 850C. It was found that the surface strain hardening associated with mechanical polishing increases the fatigue limit of this alloy at temperatures below 750C and decreases this limit above 750C.
