Wire Mesh

Generally must be acid resistant steel, in practice, often called the weak medium corrosion resistant steel stainless steel, and called the resistance to chemical corrosion medium steel acid-resistant steel. Commonly used Stainless steel gas-liquid filter mesh material has: 304, 304 l, 304, 316, 316 l, 316, etc. Stainless steel gas-liquid filter mesh product features are: weak corrosive medium such as air, steam, water resistance and acid, alkali, salt and other chemical etching medium corrosion of the steel. Also called acid-proof stainless steel. In practical application, often called the weak corrosive medium corrosion resistant steel stainless steel, and called the resistance to chemical corrosion medium steel acid-resistant steel. Due to the chemical composition on the difference between the two, the former does not necessarily medium resistance to chemical corrosion, while the latter are generally not rust. The corrosion resistance of stainless steel depends on the alloy element content in the steel. Chromium is the basic element to stainless steel for corrosion resistance, while about 12% chromium content in steel, chromium and oxygen effect of corrosive medium, in the steel surface to form a thin layer of oxide film (since the passivation film) can prevent steel substrate further corrosion. Commonly used alloying elements except chromium and nickel, molybdenum, titanium, niobium, copper, nitrogen, etc., in order to meet the requirements of various applications on the microstructure and mechanical properties of stainless steel. The Stainless steel gas-liquid filter mesh must be acid resistant steel in general.
