Stainless Steel 316 features
316 stainless steel has a better resistance to chemicals and chlorides (like salt) than ss 304. When it comes to applications with chlorinated solutions or exposure to salt, grade 316 stainless steel is considered superior, so it is usally called marine grade stainless steel.
When it comes to pipe fittings, stainless steel 316 offers plenty of advantages over other materials thanks to its superior corrosion resistance and mechanical properties which make it ideal for use in demanding industrial applications – particularly those involving contact with saltwater or corrosive elements. Not only does this material provide excellent protection against corrosion but it also eliminates the need for additional protective coatings or painting due to its natural resistance against rusting when exposed to environmental conditions such as moisture or salt air.
