The resistance of Types 304 and 316 stainless steels to crevice corrosion in natural waters
Types 304 and 316 stainless steel are widely and successfully utilized in piping and equipment to handle fresh waters. Occasionally, conditions are encountered that cause localized attack, usually crevice corrosion, of these alloys. In fresh waters of up to 1000 mg/L chloride content, Type 316 is resistant to crevice corrosion in severe geometries. Type 304 is also resistant in 80 pct or more of metal-to-nonmetal crevice sites in the same waters. Initiation of crevice corrosion in Type 304 is more dependent on existence of a critical crevice geometry, i.e., a gap dimension (tightness factor) than on the chloride ion concentration up to at least 1000 mg/L. These tests showed Type 304 and Type 316 to be more resistant than earlier electrochemical tests reported by others.
