This study discusses multiaxial low cycle fatigue (MLCF) life of SUS316 stainless steel under proportional and non-proportional loadings at room temperature. Strain controlled MLCF tests were carried out using SUS316 hollow cylinder specimen with 6 types of strain paths. Reduction in failure lives were observed accompanying by additional hardening due to non-proportional straining. However, mean strain effect under T-shaped strainings, where 1, 10 or 100 cycles of reversed straining were applied with tensile constant straining, was reduced with increasing cycles of reversed torsion straining.
