WebThe combined action of freeze–thaw cycles and chloride-induced corrosion are generally recognized as one of the main causes of the degradation of the mechanical properties and seismic performance of reinforced concrete (RC) structures in the northern frozen … WebChloride induced pitting corrosion is a known issue with austenitic stainless steel alloys such as 304 and 316. Alloy 316 is somewhat more resistant to the initiation of chloride-induced pitting than is alloy 304, but not fully resistant. Pitting corrosion is a localized form of galvanic corrosion. It is initiated at a local imperfection in the
