2. Chemical composition
The corrosion resistance of stainless steel wafer is mainly determined by its alloy composition (chromium
nickel, titanium, silicon, aluminum, manganese, etc.) and internal structure.Chromium has a high chemical
stability, can form a passivating film on the steel surface, so that the metal and the outside isolated,
protect the steel plate is not oxidized, increase the corrosion resistance of the steel plate.After r the
passivation film is broken, the corrosion resistance decreases.
