Can anyone tell me what makes a stainless cast iron wok stainless?

Dear, true stainless steel is made by oxidizing cast iron through high temperature. In fact, it is the surface layer that is oxidized. It will still rust over time. Really stainless steel pots are just a little better than ordinary cast iron pots. Iron will rust. If you want to avoid rusting, after using the pot, simmer the pot surface over a slow fire and rub a few drops of cooking oil on the pot surface to protect you from rust. rust. We know nothing but iron pots. ---Iron Kitchenware
