There are generally two kinds of stainless iron pots, one is that the surface of the pot is coated, and the other is that the type of iron used to make the pot is similar to that of stainless steel, that is, the carbon content contained in the iron is well controlled. If it is a coated iron pan, it is likely to be toxic if used improperly. For example, if the dry pot is heated by high temperature fire for a long time, the coating may decompose, and the decomposed organic matter is generally toxic, which will enter the food. Stainless steel iron pans without coating are generally less toxic.

In fact, the iron pot rusts, and the iron element we need is the iron trioxide in the rust. Therefore, gold pots and silver pots are not as good as iron pots.
