1. From the perspective of foreign and domestic brands, WMF, Fishler and Zlilun are all better works. First, the materials are good. Second, advanced technology. Therefore, the pot made is also more durable and easy to use. But the price is also very high, and the wok is around 1500-3500. There are gentlemen from Ryder Company and Shunfa from Foshan, China. The materials are the same, but the price is half lower. You can go to department stores or high-end shopping malls to find out, and Taobao can also find it.

2. In terms of material, stainless steel cookware has the best hardness and corrosion resistance, and no coating is needed. The best steel is medical grade stainless steel1810; Only alloy pots and pans need coating. This kind of coating is called Teflon, which is applied to achieve the effect of uniform heating and non-sticking. If the temperature is too high, harmful gases will be released. In addition, you can't contact with a metal spatula, otherwise it will easily cause the coating to fall off, which is very troublesome, but its price is low. Half of this pot is in 150-550 yuan. After coating, Astor and Supor are the most complete products now, which are commonly found in supermarkets.

I wonder if this analysis is clear enough. I hope it helps you.
