Summary
Chloride stress corrosion cracking (Cl-SCC) is a form of localised corrosion that occurs most often in stressed austenitic stainless steels in aqueous, chloride-containing environments above approximately 50°C (122ºF). The result of the cracking is ultimately brittle failure of a very ductile material. The cracking is typically transgranular and highly branched, but can be intergranular or mixed mode in some cases.
