Strictly speaking, theoretically there is no such thing as stainless steel. Generally, manufacturers prevent rust by adding a coating to the surface of the pan. After the pan has been burned at high temperatures, the non-metallic material on the pan is burned off, and the pan naturally tends to rust. This is not the problem of people producing pot manufacturers. (General stainless steel is in the ordinary steel with nickel and chromium components to increase the antioxidant properties of steel, because I'm not the production of pots and pans so I do not know why the manufacturers do not use what we usually call stainless to produce pots and pans. I think it's because producing pots from stainless steel is supposed to produce health hazards because both metals, nickel and chromium, are toxic so that means that stainless pots may not be good for your health). I hope this is helpful.
