The commonly used stainless steel barbecue nets are divided into 304 and 201 raw materials. In practice, the raw materials are different. The quality of 304 stainless steel is better, but the cost is also more expensive. 304 is imported stainless steel, and 201 is domestic stainless steel.

304 is composed of 18Cr-9Ni, stainless steel is a widely used product, mainly used in 0 food production equipment, Xitong chemical equipment, nuclear energy, etc. 201 is high in manganese, the surface is very bright with dark and bright, and high in manganese is easy to rust. 304 contains more chromium, and the surface appears matte and does not rust. Putting the two together makes sense. The important thing is that the functions are different. The function of the 201 is not very good, so the price is cheaper.
Because 201 contains low nickel, the price of 304 is lower. The difference between 201 and 304 is simply a matter of containing nickel and not containing nickel. And the price of 304 is now going to be expensive, but 304 can be less likely to rust during use. (It can be tested with potion) Stainless steel is not easy to rust because chromium-rich oxides are formed on the surface of the steel body to maintain the steel body.
