chloride-induced stress corrosion cracking

Chloride-induced stress corrosion cracking (SCC) is a failure process where materials, especially metals like stainless steel, develop cracks due to the combined effects of tensile stress, corrosion, and chloride ions (found in salt). When metal is under stress and exposed to chlorides, it can crack gradually from within, even without obvious damage or high temperatures. This type of cracking can compromise the structural integrity of components such as pipelines or tanks in salty environments, leading to sudden failures if not properly managed. It’s a complex interaction of mechanical stress and chemical attack by chloride ions.
