Stainless steel not only has strong chemical stability, but also has sufficient strength and plasticity, and has stable mechanical properties at a certain high or low temperature. Some grades of this kind of steel can also be used as heat-resistant steel (including austenite, ferrite, martensite and precipitation hardening); Some can be used as high-quality low temperature steel, and their corrosion resistance is still excellent during use.

The stainless steel pot contains a certain amount of chromium alloy element in this type of steel, which can form a solid oxidation film (passivation film) on the steel surface that is insoluble in some media, so that the metal can be isolated from the external media without chemical action.
