Why does stainless steel spring have corrosion resistance?

Why does stainless steel spring have corrosion resistance?

All metals react with oxygen in the atmosphere to form an oxide film on their surface. Unfortunately, the iron oxide formed on ordinary carbon steel will continue to oxidize, leading to the expansion of corrosion, and finally forming holes. The surface of carbon steel can be protected by coating with paint or anti-oxidation metals (such as zinc, nickel and chromium), but as we all know, this protection is only a thin film. If the protective layer is damaged, the steel below will start to rust.
