Types of Corrosion found in Stainless Steel & Nickel Alloy

Crevice corrosion is a form of localized corrosion and occurs under the same conditions as pitting, i.e., in neutral or acidic chloride solutions. However, attack starts more easily in a narrow crevice than on an unshielded surface. Crevices, such as those found at flange joints or at threaded connections, are thus often the most critical sites for corrosion.
