why stainless steel knotted rope mesh will blacken?

Stainless steel knotted rope mesh, mainly from the stainless steel rope mesh material analysis, stainless steel is mainly composed of three elements, iron, nickel, chromium, according to different shares of production, and then the product function will be different.To get more news about stainless steel knotted rope mesh, you can visit boegger.net official website.
For example: under the condition of constant iron content, the higher the chromium content, the brighter the stainless steel knot mesh, and the higher the nickel content, the darker it will be; if the content of chromium and nickel remains unchanged, the increase of iron content will also darken, and then affect its function.
So after understanding the above material problems, let's analyze why stainless steel knotted rope mesh will blacken?
One of the conditions: most of the blackening is caused by its oxidation, that is to say, the iron contained in it will be oxidized sensitively when heated, and there will be no sign of rust.
There are two conditions: in the production process, the smoothness of the wire drawing machine is not good enough, the friction resistance is too large, and the surface of stainless steel knotted rope mesh is severe, which leads to the segregation of metal elements in the steel wire, the alloy composition is separated, and then the surface is blackened.
