Summary

Laboratory tests demonstrated that austenitic stainless steel becomes susceptible to stress-corrosion cracking in dilute sodium chloride solutions (>2 ppm) when the surface of the metal has been dry ground with an abrasive grit. Applied stress is not required to produce these cracks. Two stages of transgranular crack development were observed. First, visible anodic sites formed on the specimen surface in areas where inclusions were present, and cracks initiated at these sites. Second, corrosion occurred within the crack and hydrolysis of corrosion products produced an acid condition. As corrosion continued, subsurface pitting occurred. (auth)
