​Why does the steel wire of the stainless steel conveyor belt rust? What should I do after rusting? From a professional point of view, the higher the nickel and chromium content, the more difficult it is for stainless steel to corrode. On the contrary, those with a lower content will rust when placed in harsh environments.

Stainless steel is in the weakly corrosive medium such as air, water, steam, etc. The steel that does not rust is called stainless steel. Stainless steel is made by adding a certain content of chromium to normal carbon steel. The key reason why stainless steel has rust resistance is because steel contains chromium. Under the effect of corrosive medium, chromium forms a strong and dense oxide film on the surface of steel parts, which is called "passivation film". This film isolates the metal from the external media and prevents the metal from being further corroded. It also has the ability to self-correct. If it is damaged, the chromium in the steel and the oxygen in the medium will regenerate a passivation film, which will continue to protect it.
