The stainless steel grades used in swim pool rails and ladders are fairly impervious to swimming pool water that is in balance. The material is strong, watertight, extremely versatile, and resists corrosion, so it’s perfect for new pools. It is susceptible to rust and corrosion when it gets oxidized. I have had a 316 stainless steel trim around my pool for 28 years and it has not corroded. Stainless steel generally has a higher resistance to the effects of exposure but will still be affected by the elements. They do cost more, however the added corrosion resistance is the only way to go for salt water pools. This should prove to you that stainless steel is able to handle water exposure. Even if stainless steel is scratched and the chromium oxide layer is removed, a new chromium oxide … Stainless steel is reinforced with between 12-30% chromium, and sometimes has some nickel and manganese. Apart from industrial plants and laboratories–which have safeguards and are built for the chemicals used–we cannot think of any. Stainless steel, however, is different. $159.96. When the rails do rust at the waterline they can be cleaned up with some wet and dry sandpaper. Is it any wonder why chemical storage rooms–when not vented properly and built with corrosion-proof materials–get such bad corrosion? Inappropriate stainless steel or finish selection; Inadequate or improper maintenance; Improper pool fabrication or installation techniques; Deficient control of water chemistry and the pool environment Stainless steel is a steel alloy that contains a minimum chromium content of 10.5%. At the moment, there are over 150 varieties of stainless steel in the market. Worldwide there have been many incidents, and several accidents, with cracking stainless steels in the swimming pool atmosphere. But in extreme environments, such as indoor swimming pools, the effects can be extreme and potentially dangerous. Related: Dehumidification Problems in Natatoriums. Chloramine Consulting exists to help architects and engineers change that paradigm. The very few reports of stainless steel corrosion in pools were usually related to poor design or workmanship. The steel rods had been pitted, causing the roof to cave in. Steel is a product of iron and carbon. Get your screws and bolts etc. Here's a chart showing pH and some common pool chemicals: If you look all the way on the left side of this chart, you will see muriatic acid is below 1.0 pH. Corrosion to stainless steel normally occurs when chlorine or chlorides are present, and nitrogen trichloride (aka trichloramine, NCl3) definitely fits that bill. For instance, exposure to seawater or pool water can cause stainless steel rusting due to the corrosive nature of chlorine in the saltwater and in pool cleaning chemicals. It’s just not the same grade. Pooled Energy | Blog | Pool Maintenance | Rust on Stainless Steel components in swimming pools. We have countless photos showing the brutality of swimming pool environments on metals. There are some great stainless steel cleaners out there. Stainless is generally unaffected by alkali and if your pool shop says that staining is due to high alkalinity, they are wrong. Put in some handrails last year on a saltwater pool and started seeing rust on the rails at the waterline after three weeks.
