The corrosion resistance of stainless steel plates mainly depends on their alloy composition (chromium, nickel, titanium, silicon, aluminum, manganese, etc.) and internal microstructure, with chromium playing a major role.
Chromium has high chemical stability and can form a passivation film on the surface of steel, isolating the metal from the outside, protecting the steel plate from oxidation, and increasing its corrosion resistance. After the passivation film is damaged, the corrosion resistance decreases.
It is required to withstand the corrosion of various acids, such as oxalic acid, sulfuric acid Iron(III) sulfate, nitric acid, nitric acid hydrofluoric acid, sulfuric acid Copper(II) sulfate, phosphoric acid, formic acid, acetic acid, etc.
Widely used in: chemical, food, medicine, papermaking, petroleum, atomic energy, construction, kitchenware, tableware, vehicles, household appliances, etc.
