Why the stainless steel wire filter will get rust

Stainless steel wire filter is generally made of relatively strong corrosion resistance. Its surface is a passivation film. In nature, they exist in the form of stable oxides, and the use conditions of stainless steel are also different.

The surface of any metal exposed to a corrosive environment will undergo electrochemical reactions or chemical reactions and will be subject to varying degrees of corrosion. The weak corrosion resistance of the passivation film on the surface of the stainless steel filter screen will form pitting with the self-excited reaction, and then small pores will be formed, plus the approach of chloride ions to form a strong corrosive solution, so that Accelerates corrosion rate. There are also intergranular cracks inside the stainless steel filter. All of the above will damage the passive film on the surface of the stainless steel filter.

The environmental impact of the stainless steel filter mesh production. After long-term processing, many contaminants such as oil, carbon black, and dust will also accumulate on the convection plate and the hearth. If it is not cleaned in time, the same will fall on the stainless steel plate.
