Who says what is the principle of stainless cast iron wok?

Dear, true stainless means that cast iron is oxidized at high temperature, but the surface layer is actually oxidized. It will rust over time. Real stainless steel is only a little better than ordinary cast iron pots. Iron rusts. If you want to avoid rust, usually use a pot, slowly boil the water on the surface of the dry pot, and wipe the surface of the pot with a few drops of cooking oil to keep you away from rust. We know nothing except the pot. -Iron Man Kitchenware
