Stress Corrosion Cracking of Stainless Steels in Swimming Pools

The use of 'stainless steels' to withstand corrosive environments is well established in many constructional applications involving loadbearing components. It would appear, however, that structural engineers are frequently not well informed about the nature and properties of these materials. The generic term, stainless steel, is actually used to describe a wide range of alloys, based on iron with controlled proportions of chromium and usually other elements such as nickel and molybdenum. Their properties vary considerably with composition and it is unfortunate that the epithet 'stainless' has sometimes been interpreted too literally. It should be recognised that the corrosion resistance of these alloys is dependent on the integrity of an invisibly thin surface film of oxide and, in circumstances that cause this protective layer to be undermined, various forms of localised attack may develop.
