Titanium steel stainless steel gauze, titanium steel gauze 26 mesh
stainless steel window Yarn has the ability to resist atmospheric oxidation, that is, rust resistance, and also has the ability to corrode in the medium containing acid, alkali, and salt, that is, corrosion resistance. However, its corrosion resistance varies with its chemical composition, interaction state, service conditions and environmental medium type. E.g. 304 Steel pipe In a dry and clean atmosphere, it has excellent corrosion resistance, but if it is moved to the seaside area, it will rust soon in the sea fog containing a lot of salt; The 316 steel pipe performs well. Therefore, not any kind of stainless steel can resist corrosion and rust in any environment.
Stainless steel is resistant to corrosion by forming a thin, firm, fine and stable chromium rich oxide film (protective film) on its surface to prevent oxygen atoms from continuing to penetrate and oxidize. Once for some reason, this kind of film is constantly damaged, oxygen atoms in air or liquid will continuously penetrate or iron atoms in metal will continuously separate, forming loose ferric oxide The metal surface is continuously corroded.
