Why does stainless steel rust?
Under normal circumstances, stainless steel will not rust. However, if it is not used or maintained properly or the environment in which stainless steel is located is too harsh, stainless steel may rust. When we see yellow or orange rust spots on the surface of steel, we can quickly confirm that this is a sign of rust.
Why does stainless steel rust? First, let us understand the structure of stainless steel
Stainless steel is a crystalline solid composed of atoms arranged like a puzzle toy. In addition to iron, it also contains metal components such as chromium, nickel, and titanium. The chromium-nickel element has anti-rust function. It forms a protective passive film to prevent stainless steel from rusting.
Under normal circumstances, stainless steel will not rust as long as this film is not damaged, cracked or contaminated by impurities. However, if the passive film is damaged due to improper use or maintenance, stainless steel will rust.
It is recommended to use stainless steel or better when used in places with acid and alkali. Generally no problem in normal environment. Or
It’s better to use less as it will rust easily. Be careful to keep stainless steel away from acids and alkalis.
