What Is Crevice Corrosion? As its name suggest, crevice corrosion is localised, generally in a stagnant microenvironment where acidic conditions, or a depletion of oxygen in a crevice can lead to rusting.
The combination of tensile stress and a specific corrosive environment can crack stainless steels. This mode of attack is termed stress corrosion cracking (SCC). The most common environmental exposure condition responsible for SCC of stainless steels is the presence of chlorides. Although no stainless steel grade is totally immune to chloride SCC, the relative resistance of stainless steels varies substantially. Jul 18, 2017 · Crevice corrosion is a localized corrosion attack at or very near the gap, or crevice, between joined surfaces that are exposed to corrosives like air or water. It occurs when chemical concentrations differ between separate points near joined surfaces.
