Stainless steel filters mesh are widely used in the petroleum industry. The coal mining industry is characterized by acid and alkali resistance and corrosion resistance. However, stainless steel filters mesh are available in a variety of materials, including nickel, 2 nickel, 4 nickel, and 302 304 316 316L, which result in corresponding changes in service life depending on the material of the product. But in general, we can only watch the peace of the face from the outside, the actual material is difficult to distinguish from the surface with the naked eye, we must take a certain sample, use the corresponding instrument to test his qualitative material. Among them, the identification of syrup is a common way to identify stainless steel wire mesh. Drop a drop of water on the mesh surface, then rub it with copper sulfate. If it does not change color after rubbing, it can be determined that it is high quality stainless steel. If it turns purple, non-magnetic is high manganese steel, usually less than one kilogram in the market. Yuan stainless steel wire mesh, you can conclude that it is not a real stainless steel wire mesh.
