Real stainless steel products should be able to be used for hundreds of years without rusting. However, the stainless steel we see on the market can still be rusted and corroded, but under normal circumstances, the corrosion rate is very slow.
Whether stainless steel is easy to rust, the content of chromium is the key. The stainless steel component contains a relatively high proportion of chromium, so under normal circumstances, its surface is always in a passivated state, so it will not rust.
If the chromium content is low, that is inferior stainless steel, its surface cannot form a dense enough passivation film to protect it. It will still rust. Another situation is that stainless steel encounters very active substances, such as daily salt, which contains high chlorine or fluoride ions. Even high-quality stainless steel with high chromium content will destroy the passivation film on its surface. The surface of stainless steel is in an active state. At this time, stainless steel will not only rust, but also dissolve heavy metal ions that are harmful to the body.
