The effect of coolant temperature on the susceptibility of stress corrosion cracking (SCC) of SUS316L wa investigated by means of slow strain rate test (SSRT). Results indicated a temperature dependence with susceptibility peaked around 613K (340^oC) at pressurized condition. Further, intergranularly fracture mode was recognized.
