Stainless steel is well-known for its corrosion-resistant properties and has seen widespread application in many situations. In a special user survey of stainless steel performance, the authors examined its use in municipal potable water distribution systems, municipal potable water treatment plants, building water supply systems, wastewater treatment plants, household plumbing systems, dams, locks, and hydroelectric plants. Type 304/304L (UNS S30400/30403) and type 316/316L (UNS S31600/31603) are the principal materials used. The authors found cases of under deposit corrosion at incompletely fused circumferential welds, corrosion at brazed joints where acid chloride fluxes had been used, corrosion from excessive chlorination, corrosion from iron embedded during fabrication, and microbiological corrosion from water left standing after hydrotesting. The incidence of such problems in the approximately 70,000 tons of stainless steel currently used per year worldwide in these applications is estimated to be less than 0.01%.
