What about the main definition of 304 stainless steel perforated metal mesh answers are as follows: higher ductility, resistance and mechanical strength, stainless steel perforated metal mesh surface brightness. Corrosive acid and alkaline gases, solvents and other media. A non-rusty steel is easy, but not definitely not rust. Stainless steel corrosion resistance depends on the arrangements for the first layout that alloy composition and internal, from the primary effect of chromium. Chromium has a high chemical stability, constitute a passive film on the steel surface, the metal barrier and open to the outside world, the protection of steel perforated metal mesh is not oxidized, to add anti-corrosion steel perforated plate. After passivation film damage, corrosion resistance is reduced.
