The surface of stainless steel usually has a dense passivation layer. The reason why it does not rust is because this passivation layer can resist the erosion of the natural environment. In the steel manufacturing process, the pickling process occurs on the surface of the mesh belt during the pickling process. Form a passivation film. If the mold is not smooth, this protective layer will naturally be destroyed, and of course it will rust. There are many reasons for the rust of stainless steel, many of which are not the rust of the stainless steel itself, but the mixing of other substances in the subsequent processing. Secondly, the main reason why stainless steel does not rust is the chromium oxide on the surface. Generally speaking, when the Cr content in alloy steel exceeds 12%, it can be called stainless steel. Some surface treatments will destroy the oxide layer on the surface to make it brighter, and it is easier to rust, but the oxide layer will regenerate over time. This is the reason for the rust of the stainless steel mesh belt. Due to fierce market competition, many people in order to save costs and achieve the purpose of attracting customers at low prices, the steel of stainless steel mesh belts is gradually decreasing. For example, when the content of non-metallic impurities in steel is too high, the metallographic structure will be deviated. The source of strip steel is more complicated, and the quality of steel is the package.
