The corrosion resistance of 304 stainless steel plate

304 stainless steel plate is required to be able to withstand the corrosion of oxalic acid, sulfuric Acid-Ferric sulfate, nitric acid, nitric acid-hydrofluoric acid, sulfuric Acid-Copper sulfate, phosphoric acid, formic acid, acetic acid and other acids. 304 stainless steel plate is widely used in chemical, food, pharmaceutical, paper-making, petroleum, atomic energy and other industries, as well as construction, kitchenware, tableware, vehicles, household electrical appliances and other components.

The surface of 304 stainless steel plate is smooth and clean, with high plasticity, toughness and mechanical strength, and resistance to acid, alkaline gas, solution and other media corrosion. 304 stainless steel plate is an alloy steel that does not rust easily, but it is not mean never rusty.

The corrosion resistance of 304 stainless steel plate mainly depends on its alloy composition (chromium, nickel, titanium, silicon, aluminum, etc.) and internal structure, and chromium plays a major role. Chromium has a high chemical stability, can form a passive film on the surface of 304 stainless steel plate, so that the metal is isolated from the outside, protect the 304 stainless steel plate from oxidation, increase the corrosion resistance of 304 stainless steel plate. After the passivation film is destroyed, the corrosion resistance decreases.
