Why does stainless steel flange rust

Views: 0    

The stainless steel flange is not completely rust-proof, but its oxidation resistance is stronger than that of ordinary steel, so it is called stainless steel.

Stainless steel not only can resist atmospheric oxidation, but also can corrode in acid, alkali, and salt media. However, the size of its corrosion resistance varies with the chemical composition of the steel itself, the interaction state, the use conditions, and the type of environmental media. For example, the 304 flange has good corrosion resistance in a dry and clean atmosphere, but it will be moved to the seaside area. In the sea with a large amount of salt fog, it will quickly rust, and the 316 flange performs well. . Therefore, it is not any kind of stainless steel, it is resistant to corrosion and rust in any environment.
