The SCC susceptibility of type 321 stainless steel in acidic chloride solution has been studied by slow strain rate testing (SSRU and SEM. During the slow rate tensile process, the specimen was polarized with different potential pefturbation modes such as cyc1ic potential scan and cyclic potential step methods. The results indicated that the potential scan rate or step frequency played an essential role in the initiation and propagation of crack.
