410 cold rolled super duplex hairline finish stainless steel sheet 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, the size of its corrosion resistance is changed with the chemical composition of its steel itself, processing state, use conditions and the type of environmental media. Relying on a very thin, firm and stable chromium-rich oxide film (protective film) formed on its surface to prevent the continuous penetration and oxidation of oxygen atoms, the ability to resist rust is obtained. Once the film is continuously damaged for some reason, the oxygen atoms in the air or liquid will continue to infiltrate or the iron atoms in the metal will continue to separate out, forming loose iron oxide, and the metal surface will be continuously corroded. Many of the above situations can cause damage to the protective film on the surface of stainless steel and cause rust.
Therefore, in order to ensure that the 410 cold rolled super duplex hairline finish stainless steel sheet has a permanent bright metal surface and is not rusted, we recommend:
1. The stainless steel surface must be cleaned and scrubbed frequently to remove attachments and eliminate external factors that cause corrosion.
2. The chemical composition of some stainless steels on the market cannot meet the corresponding national standards, so it will also cause rust, which requires users to carefully choose products from reputable manufacturers.
