AISI Type 309S is austenitic chromium-nickel stainless steels that provide excellent corrosion resistance and heat resistance as well as good strength at room and elevated temperatures. Since this material is widely used in high-temperature applications (e. g. gas turbine combustor), creep life analysis of the part is important. The accuracy of FEM analysis and creep life estimation is extremely related to the strain-stress curve of material at different temperatures. In the present research, several tensile tests have been performed with bar test specimens and mechanical properties of Steel 1.4835 (309S) at room and elevated temperatures have been investigated
