Frameless door stainless steel patch fittings http://www.fs-broadocean.com/Patch-fittings/patch-fittings-with-lock-for-glass.html basic description of atmospheric corrosion
Stainless steel resistance to atmospheric corrosion basically varies with the amount of chloride in the atmosphere. Therefore, corrosion of stainless steel near marine or other chloride pollution sources is extremely important. (Patch fittings with Bottom Inserts) A certain amount of rainwater is important only if the chloride concentration on the surface of the steel works. The rural environment 1Cr13, 1Cr17 and austenitic stainless steels can be adapted to various applications and their appearance will not be significantly changed. Therefore, the exposed stainless steel in rural areas can be selected based on the market availability, mechanical properties, manufacturing process performance, and appearance of the patch fittings with lock for glass swing door. Industrial environment In the industrial environment without chloride pollution, 1Cr17 and austenitic stainless steels can work for a long period of time, basically remain rust-free, and may form a dirty film on the surface, but when the dirty film is removed, it still maintains the original Bright appearance. (Patch fittings for frameless glass doors) will cause stainless steel rust in industrial environments where chlorides are present. Marine Environment 1Cr13 and 1Cr17 stainless steels will form a thin rust film in a short period of time but will not cause significant dimensional changes. Austenitic stainless steels such as 1Cr17Ni7, 1Cr18Ni9, and 0Cr18Ni9 may show some rust when exposed to the marine environment. Rust is usually shallow and can be easily removed.
