The main differences between stainless steel barbecue net 201 and 304 are as follows:
1. Specification: the commonly used stainless steel barbecue nets are divided into two types: 201 and 304. In fact, the ingredients are different. 304 has better quality, but the price is expensive, and 201 is worse. 304 is imported stainless steel and 201 is domestic stainless steel.
Main differences between stainless steel barbecue mesh 201 and 304
2. 201 is composed of 17cr-4.5ni-6mn-n, which is a Ni saving steel and an alternative steel to 301 steel. It is magnetic after cold processing and is used for railway vehicles.
3. 304 is composed of 18cr-9ni, which is the most widely used stainless steel and heat-resistant steel. Used for food production equipment, Xitong chemical equipment, nuclear energy, etc.
4. 201 has high manganese content, bright surface with dark brightness, high manganese content and easy to rust. 304 contains more chromium, the surface is matte and does not rust. When the two are put together, there is a comparison. The most important thing is that the corrosion resistance is different. The corrosion resistance of 201 is very poor, so the price is much cheaper. Because 201 has low nickel content, the price is lower than that of 304, so the corrosion resistance is not as good as that of 304.
5. The difference between 201 and 304 is the problem of nickel. Moreover, the price of 304 is now relatively expensive, generally close to 50000 a ton, but 304 can at least ensure that it will not rust in the process of use. (liquid medicine can be used for experiment)
6. Stainless steel is not easy to rust because chromium rich oxide is formed on the surface of the steel body to protect the steel body. Material 201 belongs to high manganese stainless steel, which has higher hardness than 304, high carbon and low nickel.
7. Different compositions (mainly distinguish 201 and 304 stainless steels from carbon, manganese, nickel and chromium).
