Stress-corrosion cracking of austenitic alloys in an oxygen-free carbon dioxide environment containing chloride ions was studied under static conditions. Stiffness and X-ray measurements supported results obtained from SEM photomicrographs indicating that the CT specimens loaded to a stress intensity of 22 ksi-in.5 were not susceptible to SCC in this environment. These alloys were also evaluated for their SCC resistance in boiling MgCl₂ and NaCl solutions. Results of this study indicated that alloys containing higher nickel contents were more resistant to chloride SCC.
