magnetism stainless steel corrosion conditions

All metals and oxygen in the reaction atmosphere , an oxide film is formed on the surface . Unfortunately , the iron oxide formed on carbon qiyi magnetism stainless steel is continued oxidation, rust expanded , forming holes. You can use paint or oxidation-resistant metals ( eg , zinc, nickel and chromium ) plating to ensure the steel surface , but, as people know, this protection is only a film . If the protective layer is damaged , the following steel began to rust . Corrosion resistance of qiyi stainless steel 304 sheet depends on chromium, but because chromium is an integral part of steel, so the protection methods vary.
