304 stainless steel tube is more and more used in everyone's daily life. Because it's bright and easy to wash, not easy to rust, not only the surface is beautiful, but also strong. However, the 304 stainless steel tube is not absolutely rust-free. Under what circumstances will the 304 stainless steel tube rust?

Why does 304 stainless steel tube rust

304 stainless steel tube is not forever rusted, the chromium-rich oxide film (protective film) on its surface has the ability to resist atmospheric oxidation, and also has the ability to resist corrosion in the medium containing acid, alkali, and salt. The size of its anti-corrosion ability is changed with the chemical composition, processing shape, operating conditions, and type of environmental media of the steel itself. When the protective film is damaged, rust will naturally occur.

The surface of the stainless steel pipe has a thin, firm, dense, and stable chromium-rich oxide film. The reason why the stainless steel pipe is rust-proof is that this oxide film prevents oxygen atoms from infiltrating and oxidizing and causing rust. The addition of nickel and chromium to the stainless steel tube changes the structure of the high-chromium steel so that the corrosion resistance and process performance of the stainless steel tube are greatly improved. The rust of the stainless steel tube is oxidized or corroded. It is good that it has enhanced anti-oxidation and corrosion resistance and is not easy to rust, which is why the 304 stainless steel tube is not easy to rust.

The above is the content of why 304 stainless steel tube rusts and the principle of anti-rust. There are many stainless steel tube companies in the market, and the quality of each stainless steel tube is different. Guaranteed stainless steel pipe production company to avoid being deceived.
