The material of stainless steel wire mesh varies depending on the usage conditions and the type of environmental medium

304 stainless steel wire mesh has the ability to resist atmospheric oxidation, that is, stainless steel also has the ability to corrode in media containing acid, alkali, and salt, that is, it is corrosion-resistant. However, its corrosion resistance varies depending on the chemical composition, mixing state, usage conditions, and type of environmental medium of the steel itself. For example, stainless steel wire has absolutely excellent rust prevention performance in dry and clean air, but it will be transferred to the seaside. There is a lot of salt in the sea mist, which will soon rust; 316 stainless steel wire is better. Therefore, not all stainless steel mesh can resist corrosion and rust in any environment. The 304 stainless steel mesh produced by the stainless steel mesh factory is a thin mesh formed on its surface, which is a strong and stable chromium oxide film (protective film) that can prevent the continuous penetration and oxidation of oxygen atoms and has the ability to resist corrosion. Once for some reason, the membrane layer is constantly destroyed, oxygen atoms in air or liquid continue to penetrate, or iron atoms in metal continue to separate, forming loose iron oxide, the metal surface is constantly corroded. The damage forms of surface facial mask are various, and the following are common in daily life. The surface of 304 stainless steel wire mesh is coated with dust or different metal particles containing other metal elements. In humid air, the condensate between the attachment and the 304 stainless steel screen is connected to the micro battery, causing an electrochemical reaction and damaging the protective film, which is called electrochemical corrosion. Organic juices (such as melons, soup, phlegm, etc.) adhere to the surface of stainless steel wire mesh, forming organic acids in the presence of water and oxygen, which can corrode the metal surface for a long time. The surface of ordinary stainless steel mesh is coated with substances such as acid, alkali, and salt, such as alkaline water and lime water, which can cause local corrosion.
