Many stainless steel mesh belts encounter a problem after being used for a while: metal oxidation is inevitable. However, stainless steel mesh belts overcome this issue. Why can stainless steel mesh belts resist corrosion? As is well known, all metal mesh belts undergo an oxidation reaction with oxygen (O2) in the air, resulting in the formation of corresponding oxides; for example, iron forms rust when exposed to humid air. Of course, the conveyor belts used in our production are no exception; generally, when metal is exposed to air, an oxide film forms on its surface. However, this protection is merely a thin film protection. If the protective layer cracks or is damaged, the steel inside begins to rust. The corrosion resistance of stainless steel mesh belts depends on the oxidization-resistant metal chromium mentioned above; however, since chromium is an essential component of stainless steel mesh belts, the methods used for protecting them also vary. When the chromium addition level reaches around 10%, the steel’s resistance to air corrosion increases significantly. However, at higher chromium contents, although its corrosion resistance can still be improved, the increase is not as significant. Colleagues, once the surface layer is damaged, the exposed stainless steel mesh belt surface will undergo an oxidation reaction with the air in order to repair itself, re-forming this oxide \"passivation film\" that continues to provide excellent protection. The emergence of stainless steel mesh belts brought hope for corrosion prevention of such belts, significantly improving production efficiency and reducing costs.
