A safe choice in swimming pool environments

In swimming pool environments, the selection of the right grade of stainless steel can be safety-critical. European standard EN 13451-1 now provides guidance in the choice of stainless steels grades in this area of application. It makes it clear that there is a wide range of corrosive conditions. For accessories in external swimming pools, the conditions are relatively benign and often a standard austenitic stainless steel grade such as 304L can be adequate. Grade 316L is a common option not only for the pool as such, but also for equipment and accessories in indoor swimming pools. It can be used in the splash zone or where the material is cleaned regularly. However, load-bearing elements that are not accessible for regular cleaning, for instance fasteners of suspended ceilings, are exposed to corrosive conditions similar to those in road tunnels. The accumulation of chloride-containing deposits makes indoor swimming pools one of the most corrosive environments to be found in buildings. For these applications, high-alloyed stainless steels of the 6 % molybdenum type are a must.
