Why stainless steel pipe fittings tee also rusts

　　stainless steel pipe fittings tee is also rusty under certain conditions.stainless steel pipe fittings tee has the ability to resist atmospheric oxidation - that is, rust - free, and also has the ability to corrode in the medium containing acid, alkali and salt - that is, corrosion resistance. However, the size of its corrosion resistance varies with the chemical composition of the steel itself, the addition state, the use conditions and the types of environmental media. Such as the 304 steel pipe, in the dry clean atmosphere, have absolutely excellent anti-corrosion ability, but it will be moved to the beach area, with large amounts of sea salt fog, will rust quickly; and the good performance of 316 steel pipe. Therefore, not any kind of stainless steel pipe fittings tee, in any environment, can be corroded and not rusty.

　　Stainless Steel Pipe Fitting SS304 BSPT NPT Thread Screw Tees is a very thin layer formed on the surface and the stability of the fine solid chromium rich oxide film (protective film), to prevent the infiltration of oxygen atoms, to oxidation, and the ability to obtain anti-corrosion. Once there are some reasons, the thin film is constantly damaged. The oxygen atoms in air or liquid will continuously infiltrate or the iron atoms in the metal will continuously separate out, forming loose iron oxide, and the metal surface will also be corroded constantly.
