The conditions that high-quality stainless steel wire mesh should have: The corrosion resistance of the chemical composition stainless steel decreases with the increase of carbon content. Therefore, the carbon content of most stainless steels is low, and the maximum is not more than 1.2%. Some carbon content even Less than 0.03%. The main alloy element in stainless steel is Cr. Only when the Cr content reaches a certain value, the steel has corrosion resistance. Therefore, the general Cr content of stainless steel is at least 10.5%. Stainless steel also contains Ni, Ti, Mn, N, Nb, Mo, Si, Cu and other elements.
Because the stainless steel material has its own unique place, the 304 stainless steel wire mesh processed from the machine has high wear resistance, long service life, very precise mesh, uniform structure, no curl, easy application, and has Static electricity, acid resistance, high temperature resistance, abrasion resistance and other properties, because of this, in recent years, stainless steel wire mesh has been widely used in coal, fuel, chemical, food, pharmaceutical, machinery production and other industries as mining screening equipment.
But not any kind of stainless steel can resist corrosion and rust in any environment.
Stainless steel is an extremely thin, strong, dense and stable protective film formed on its surface to prevent the oxygen atoms from continuing to infiltrate and oxidize, and to obtain the ability to resist corrosion. Once for some reason, this kind of film has been continuously destroyed, oxygen atoms in the air or liquid will continue to infiltrate people or iron atoms in the metal will continuously precipitate ions to form loose iron oxide, and the metal surface will be continuously rusted. . So pay attention to maintenance when using.
