Abstract The softening of stainless steel 316 of non--detectable difference in magnitude induced by thermal pulse was found during fatigue with strain amplitude of 1.17×10~(-4) in temperature range of 333--573 K. And it occurred if the measurements of fatigue with thermal pulse were performed in range of 333--503 K. However, it will become of the hardening in range of 503--573 K. The temperature, at which hardening of the steel induced by thermal pulse emerges in fatigue process, increses with the increasing in strain amplitudes.
