Stainless steel wire cloth is a kind of metal. Metals react with oxygen in chemical common sense. An oxide film is formed on the surface. The difference is that the iron oxide formed on the ordinary carbon steel continues to oxidize, so that the rust is continuously enlarged, and finally a hole is formed. The carbon steel surface can be ensured by electroplating with paint or oxidation resistant metals (e.g., zinc, nickel, and chromium), but as is known, this protection is only a film.
If the protective layer is destroyed, the underlying steel begins to rust. The corrosion resistance of stainless steel depends on chromium, but because chromium is one of the components of steel, the protection methods are different. When the amount of chromium added reaches 10.5%, the atmospheric corrosion resistance of the steel is remarkably increased, but when the chromium content is higher, although the corrosion resistance is still improved, it is not obvious. The reason is that when chromium
is used to alloy steel, the type of surface oxide is changed to a surface oxide similar to that formed on pure chromium metal.
Such a densely viscous chromium-rich oxide protects the surface from oxidation in one step. This oxide layer is extremely thin. Through it you can see the natural luster of the stainless steel wire surface. The exposed steel surface reacts with the atmosphere to repair itself, reforming the oxide "passivation film" and continuing to protect it. Therefore, all stainless steel elements have a common characteristic, that is, the chromium content is above 10.5%.
Stainless steel wire cloth is a kind of high-strength anti-stainless steel. It is mainly used for harsh working conditions such as impact, extrusion, material wear, etc. It can also be a harsh condition and is widely used.
