316L austenitic stainless steels have been widely used as a major structural material for a SFR (Sodium Fast Reactor) due to their excellent strength, ductility, and corrosion resistance at a high temperature condition. Low cycle fatigue tests at a couple of high temperature conditions have been performed with 15% cold worked 316L stainless steel and SA(Solution Annealed) 316L stainless steel and their behaviors have been compared. The inelastic material parameters for a Chaboche's combined plasticity model were determined using test results and the analysis results were reviewed.
