Why Does the Stainless Steel Mesh Rust?

In some cases, stainless steel mesh will also "be" rusted. People who don't know the truth may think that the material is not authentic, but it is not. The following is a description of the major culprits of the rust of the stainless steel mesh.

Reason 1. The Stainless Steel mesh Has Not Undergone Solid Solution Treatment.

 

Solution treatment refers to the heat treatment process of heating the alloy to a high-temperature single-phase zone to maintain a constant temperature, so that the excess phase is fully dissolved in the solid solution and then rapidly cooled to obtain a supersaturated solid solution.

If the alloying elements are not dissolved into the matrix material, the alloy content of the matrix structure will be low, and the corrosion resistance will be poor.

 

Reason 2. There are Ammonia Ions in the Use Environment.

 

Ammonia ions mainly exist in purified liquids and gases. The use of stainless steel in the presence of ammonia ions will speed up its corrosion, and its corrosion rate even exceeds that of ordinary low-carbon steel.

 

Reason 3. Mechanical Stress Causes Its Corrosion.

 

Due to external stress loading, it will cause a large degree of self-stress damage to its processing parts and edges, causing its intergranular phase transformation; thereby destroying its own anti-corrosion performance and accelerating its rusting process. When stainless steel products are made into products, they need to be stamped, sheared, punched, stretched, ground, sheared, bent, sliced, thermally cut or welded.
