Title: Types 304 and 316 stainless steels can experience permanganate pitting in water-handling systems

Abstract

Five recent installations of types 304 (UNS S30400) and 316 (UNS S31600) stainless steel piping in industrial fresh water-handling systems experienced extremely rapid through-wall penetration by pitting corrosion. The pitting morphology showed some characteristics of microbiologically influenced corrosion, but the pits were not associated with welds. The presence of manganese in the water and the use of chlorination indicated that permanganate ion pitting was responsible.
