Stainless steel wire mesh will occasionally go dark during use. What is causing this? This is still related to the constituent elements of the raw material. The so-called main elements of stainless steel are iron, nickel, and chromium. The three metals can be produced in different proportions. The resulting stainless steel products also have different properties and different appearances.

    When the iron content is constant, the higher the chromium content, the brighter the stainless steel wire, and the higher the nickel content, the darker. If the content of chromium and nickel does not change, the content of iron will also become darker when the content of iron increases. This is the judgment of the initial appearance of the product. If the blackening occurs during use, it is caused by oxidation, that is, the iron contained in it will quickly turn black when heated and oxidized, without showing signs of rust.

    Stainless steel wire mesh and stainless steel cloth are widely used for screening and filtering under acid and alkali environmental conditions, as mud mesh in the petroleum industry, as a screen filter in the chemical and chemical fiber industry, environmental protection, minerals, aviation, paper industry, electronics, metallurgy , Electroplating industry for pickling nets, etc.

    Weaving method: plain weave, twill weave, Dutch weave (plain weave), Dutch weave (twill) 304 type generally refers to "18-8" (18% chromium, 8% nickel) mostly basic stainless steel alloy, very suitable for mesh cloth . It can be exposed outdoors and will not rust or be oxidized when the outside temperature rises to 1400 degrees Fahrenheit. Type 304L is very similar to T-304. The difference is that the carbon content is reduced, which is more conducive to weaving and re-welding.
