What kind of stainless steel is not easy to rust?

The first reason is the content of alloying elements. Generally speaking, the content of chromium is not easy to rust when it is at 10.5%.

The higher the content of chromium and nickel, the better the corrosion resistance. For example, the 304 stainless steel requires nickel between 8-10% and chromium 18-20%.

This kind of stainless steel is not easy to rust on general condition.
