The presence of molybdenum improves its resistance to pitting and crevice corrosion caused by chlorides. For this reason, it is used in numerous components exposed to water, moisture and splashes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When a ladder, handrail or swimming pool accessory is labelled as being made from AISI 316 or AISI 316L, this designation indicates the grade of stainless steel used. It is neither a trade mark nor a type of finish.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, the fact that it is AISI 316 does not mean that the material is immune to corrosion. The grade of the steel, the surface finish, the welds, the installation, the water chemistry and the maintenance all determine how it actually performs.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What does AISI 316 mean in the context of swimming pools?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">AISI is a designation used to identify different grades of steel. The correspondences normally used are:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>AISI 316:<\/strong> EN 1.4401 or UNS S31600.<\/li>\n\n\n\n<li><strong>AISI 316L:<\/strong> EN 1.4404 or UNS S31603.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">These correspondences are for guidance only. To verify the specific material of a product, you should always consult its technical data sheet or certificate.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">According to the <a href=\"https:\/\/worldstainless.org\/wp-content\/uploads\/2025\/02\/stainless-steel-grade-sheets.pdf\">quality data sheets published by World Stainless<\/a>, the usual composition is:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Element<\/th><th>Approximate content<\/th><th>Function<\/th><\/tr><\/thead><tbody><tr><td>Chromium<\/td><td>16\u201318 %<\/td><td>It forms the passive layer that protects the surface<\/td><\/tr><tr><td>Nickel<\/td><td>10\u201314 %<\/td><td>It promotes the austenitic structure<\/td><\/tr><tr><td>Molybdenum<\/td><td>2\u20133 %<\/td><td>Improves resistance to chlorides<\/td><\/tr><tr><td>Carbon steel grade 316<\/td><td>Maximum 0.08 %<\/td><td>It affects the behaviour of the welds<\/td><\/tr><tr><td>Carbon in 316L<\/td><td>Maximum 0.03 %<\/td><td>Reduces the risk of intergranular corrosion following welding<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Chromium forms an extremely thin passive layer on the surface.

Its typical resistance to chloride pitting is similar to that of AISI 316.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why is AISI 316 used in swimming pools?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">In a swimming pool, there may be a combination of constant humidity, disinfectants, splashes, temperature changes, salts and areas where water evaporates onto the metal.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">AISI 316 is used because it offers:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Greater resistance to chlorides than AISI 304.<\/li>\n\n\n\n<li>Good performance in components exposed to water.<\/li>\n\n\n\n<li>Smooth surfaces that make cleaning easier.<\/li>\n\n\n\n<li>Ease of manufacturing pipes, bends and welded components.<\/li>\n\n\n\n<li>A finish suitable for visible elements.<\/li>\n\n\n\n<li>Mechanical strength for access and support components.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The <a href=\"https:\/\/bssa.org.uk\/bssa_articles\/stainless-steels-for-swimming-pool-building-applications-selection-use-and-avoidance-of-stress-corrosion-cracking-scc\/\">British Stainless Steel Association<\/a> considers 316 to be preferable to 304 in most standard swimming pool applications.

The material of the screws, brackets, anchors and welds should also be checked.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">One example is the <a href=\"https:\/\/trypool.com\/en\/products\/barandilla-fx05-pletina\/\" data-type=\"link\" data-id=\"https:\/\/trypool.com\/producto\/barandilla-fx05-pletina\/\">FX-05 handrail with welded bracket<\/a>, made from AISI 316L stainless steel.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Waterfalls and water chasms<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Waterfalls and gorges combine water flow, humidity, joints and surfaces on which deposits can accumulate.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Trypool range includes:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/trypool.com\/en\/products\/bali-mini-waterfall\/\" data-type=\"link\" data-id=\"https:\/\/trypool.com\/producto\/cascada-bali-mini\/\">Bali Mini stainless steel waterfall<\/a>.<\/li>\n\n\n\n<li><a href=\"https:\/\/trypool.com\/en\/products\/canon-tahiti-aisi-316-without-nozzle\/\" data-type=\"link\" data-id=\"https:\/\/trypool.com\/producto\/canon-tahiti-aisi-316-sin-boquilla\/\">Tahiti AISI 316 spray head without nozzle<\/a>.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">With these products, both the visible surface and the joints and areas where water may collect must be kept clean.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Anchors, screws and fittings<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">It should not be assumed that all components of an assembly are made from exactly the same material.

It also warns that a high local concentration, even if only temporary, can damage the stainless steel.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This recommendation relates to the fittings and conditions specified by that manufacturer. It should not be automatically applied to complete systems, hydraulic circuits, structural components or products from other brands.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Before installing a fitting in a saltwater swimming pool, you must check the following:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Express authorisation from the manufacturer.<\/li>\n\n\n\n<li>Permissible salinity range.<\/li>\n\n\n\n<li>Screws and fixings.<\/li>\n\n\n\n<li>Need for a sacrificial anode.<\/li>\n\n\n\n<li>Equipotential bonding requirements.<\/li>\n\n\n\n<li>Cleaning and maintenance programme.<\/li>\n\n\n\n<li>Warranty terms and conditions.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">During commissioning, do not pour a large amount of salt next to a staircase, handrail or waterfall.
