The stress corrosion cracking (SCC) behavior of cold-worked and sensitized Type 304 (UNS S30400) stainless steels has been evaluated using the slow strain rate test. Tests were carried out in an aqueous solution of 1 N sulfuric acid (H2SO4) + 0.5 M sodium chloride (NaCl) at 30°C under various potentiostatic conditions. The effects of applied potential and cold work prior to sensitization have been investigated. These effects are discussed with respect to electrochemical and microstructural phenomena. It has been possible to determine the critical degree of deformation for the development of intergranular SCC and transgranular SCC under different electrochemical conditions.
