Why Does Stainless Steel Wire Mesh Blacken During Use?
As for the blackening of stainless steel mesh, we can analyze it from the specific material.
The first element of stainless steel in stainless steel mesh is iron, nickel and chromium. According to the different production proportion, stainless steel products have different functions and appearance.
The higher the chromium content, the brighter the color of stainless steel wire, and the higher the nickel content, the darker the color of stainless steel wire.
If the content of chromium and nickel does not change, the increase of slurry content will also turn black, which is the initial appearance judgment of the product.
If there is blackening due to oxidation in use, this is also the phenomenon that the heating oxidation included in the iron block will quickly blacken without signs of rusting.
Then there is the production process. The flatness of the wire drawing machine is not good enough, the friction resistance is too large, the surface of the stainless steel wire is seriously heated, resulting in the internal segregation of metal elements, serious alloy composition, and then blackening.
The reason for blackening of stainless steel wire mesh is not single, and needs to be considered from many aspects.
