There are many kinds of pots, including iron pot, aluminum pot, casserole, non stick pot and stainless steel pot. We Chinese people have a saying: what to cook, what to use. In fact, not only do we need to cook, but we also need to operate according to the different materials of the pot. Improper and careless operation will reduce the service life of the pot.

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.
