Austenitic stainless steels are prone to stress corrosion cracking (SCC) in chloride environments especially when residual stress or external tensile loads are present in the material. In the current study, we used synchrotron X-ray microtomography to study the SCC behavior of 304 stainless steel. NaCl and KCl salts were deposited on the specimen surface, and a ceramic crevice former was used to form the crevices, with an applied torque of 7.91 N⋅m. Then the sample was exposed to 105 ℃ with a dew point of 95 ℃ for 100 days. A crack originated from the crevice, which was carefully imaged using Synchrotron Xray tomography. The paper will report the methodology, results, and discussion of the crack propagation mechanisms.
