Main factors affecting stainless steel corrosion

Main factors affecting stainless steel corrosion

1. The content of alloying elements

Generally speaking, the chromium content of 10.5% steel is not easy to rust. The higher the content of chromium and nickel, the better the corrosion resistance. For example, the nickel content of 304 material is 8-10%, and the chromium content reaches 18-20%. Such stainless steel will not rust under normal circumstances.

2. Smelting process

A large stainless steel plant with good smelting technology, advanced equipment and advanced technology can guarantee the control of alloy elements, the removal of impurities, and the control of the cooling temperature of the billet, so that the products produced are not easy to rust.

3. External environment

A dry and ventilated environment is not easy to rust, and the air humidity is high, or the environment with high pH in the air is easy to rust.
