Extended data:
Stainless steel pot, because this steel contains a certain amount of chromium alloy elements, it can form a solid oxide film (passivation film) insoluble in some media on the steel surface, and isolate the metal from the external media without chemical action.
Some of these steels contain more chromium (Cr) and other alloying elements, such as nickel (Ni), which makes them have good chemical stability in air, water and steam, and sufficient stability in various acid, alkali and brine solutions, and can maintain their corrosion resistance even in high or low temperature environments.
Stainless steel not only has strong chemical stability, but also has sufficient strength and plasticity, and has stable mechanical properties at a certain high temperature or low temperature. Some brands of this kind of steel can also be used as heat-resistant steel (including austenite, ferrite, martensite and precipitation hardening); Some of them can be used as high-quality low-temperature steel, and the corrosion resistance is still excellent during use.
