Stainless steel stainless and corossion resistance refer to its corossion resistance when it suffer from the surrounding environmental corrossion, or the degree of retardation to corrosion, referred to as passivation.

There are many theories to explain the phenomenon of stainless steel passivation. For example, from chemical theory explain, the stainless steel resist to corrosion, that's because when stainless steel working with media, there will be a layer of film mainly Cr2O, that is, passivation film. The characteristic of this film is very thin. When the content of of Cr more than 10.5%, usually the film only a few microns; The proportion of the film is greater than the specific gravity of the metal matrix, indicating that the film is very dense, therefore, this film is difficult to be corroded dielectric breakdown, so as to effectively protect the metal matrix is not corroded.

Another example is the electronic theory, the blunt state of the metal is related to the unfilled electronic layer, in ferrochromium stainless steel, stainless steel tube, as the chrome force to absorb electrons, so that iron (Fe) atoms lost electrons were passivated. There's other saying, when Cr content in iron-chromium alloy up to 1/8(12.5%), the electrode potential can be a 0. 56V jump to +0.2 V, the improvement of the electrode potential, so that the metal in the electrolyte more stable, that is not easy to be corroded.

MAISHI WIRE MESH MANUFACTURE GROUP can produce 304, 316, etc type stainless steel wire mesh, 304, 316 and 316L stainless steel wire mesh has different element content and has different corossio resistance in acid and alkali environment.

Corrosion resistance of stainless steel is conditional. Medium type, concentration, temperature, pressure, flow rate and other factors of the differences in the corrosion of stainless steel is different. Therefore, the corrosion resistance of stainless steel is relative, not absolute, omnipotent.
