This report presents the results of a study on the elevated-temperature high-cycle fatigue behavior of Type 316 stainless steel. The primary objective was to determine the 10{sup 0}-cycle endurance strain range at 593{sup 0}C. Subsequently, other tests explored the effects of temperature, prior low-cycle fatigue damage, metallurgical variables, and weldments on this endurance strain limit. It was found that decreasing the test temperature of 482{sup 0}C raised this strain limit by about 5%, and that limited amounts of prior low-cycle fatigue straining did not affect the strain limit. The endurance limit varies from heat to heat. Pretest thermal aging in sodium and use of as-welded all weld-metal specimens both lower this strain limit by about 8%. In the course of testing, it was found that the high-cycle fatigue behavior of this steel is very sensitive to grain size and to strain rate during the cyclic hardening phase.
