Will the steel wire of the stainless steel mesh belt rust?

When brown rust spots appear on the surface of stainless steel pipes, people are surprised: they think that "stainless steel does not rust, rust is not stainless steel, it may be a problem with steel". In fact, this is a one-sided wrong view of the lack of understanding of stainless steel. Stainless steel can rust under certain conditions.
  
Now, follow this chapter to understand why stainless steel mesh belt will rust decryption process. Stainless steel is stainless steel that does not rust in weak corrosive media such as air, water, and steam. Stainless steel is made by adding a certain amount of chromium to general carbon steel. Stainless steel is not rust, the key is that the steel contains chromium.
  
Under the action of corrosive medium, chromium forms a strong and fine oxide film on the surface of steel parts, which is called "passivation film". The film isolates the metal from the external medium, preventing further corrosion of the metal. Moreover, it has the ability to self-correct. It is assumed that once damaged, the chromium in the steel will form a passive film from the beginning together with the oxygen in the medium to continue to maintain the effect.
  
Stainless steel has the ability to resist atmospheric oxidation-that is, rust resistance, and also has the ability to resist corrosion in media containing acids, alkalis, and salts-that is, corrosion resistance. Generally, stainless steel will not rust, but if it is used or maintained improperly, or the environment in which the stainless steel is located is too poor, the stainless steel may rust. When we see yellow or orange rust spots on the surface of steel, we can quickly recognize them as signs of rust. The anti-corrosion ability of stainless steel varies with its chemical composition, interaction state, use conditions and environmental medium type.
