First of all, in terms of metal treatment technology, it is impossible for iron to be oxidized at high temperature, and only aluminum alloy can be oxidized at high temperature. Therefore, Supor's stainless steel wok is really made of high-purity iron without any coating, so we can refer to the national implementation standards on which they produce this kind of wok. There are obvious marks on the outside of the box. Since there is no coating, it must be safe to use.
As for the saying that iron rusts, it was in the past when the production technology was backward. Because our people have the cooking habit of stir-frying with strong fire, pure iron pots can achieve the effect of supplementing iron and enriching blood, so it has continued to this day. But in the past, the production technology and equipment were very simple, so it became a matter of course that the iron pot rusted. However, with the improvement of production technology and technology, after high temperature, calcination and other processes, the iron pot can achieve good corrosion resistance, thus achieving non-plating and stainless. However, it is worth noting that the uncoated iron pan is most afraid of corrosion by salt and vinegar, so if you use an iron pan at home, don't store the fried vegetables in the pan for a long time, otherwise the iron pan will rust after a long time.
