　　What is the difference between 304 stainless steel and 201 stainless steel?

　　In the eyes of many consumers, there is almost no difference between 304 stainless steel and 201 stainless steel, and it is almost impossible to distinguish them with the naked eye. Here are some ways to distinguish 304 and 201 stainless steel.

　　1. Specifications: Commonly used stainless steel plates are divided into two types: 201 and 304. The actual components are different. The quality of 304 is better, but the price is more expensive, and the price of 201 is worse. 304 is imported stainless steel plate, 201 is domestic stainless steel plate.

　　2. The composition of 201 is 17Cr-4.5Ni-6Mn-N, which is a Ni-saving steel grade and a substitute steel for 301 steel. Magnetic after cold working, used in railway vehicles.

　　3. The composition of 304 is 18Cr-9Ni, which is the most widely used stainless steel and heat-resistant steel. Used in food production equipment, Xitong chemical equipment, nuclear energy, etc.

　　4. 201 has high manganese content, the surface is very bright with dark light, and the high manganese content is easy to rust. 304 contains more chromium, the surface is matte, and it does not rust. There is a comparison between the two. 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. And because 201 contains less nickel, the price is lower than that of 304, so the corrosion resistance is not as good as 304.

　　5. The difference between 201 and 304 is the problem of nickel. Moreover, the price of 304 is relatively expensive now, but at least 304 can guarantee that it will not rust during use. (Stainless steel potion can be used for experiments)

　　6. Stainless steel is not easy to rust because chromium-rich oxides are formed on the surface of the steel body to protect the steel body. 201 material belongs to high manganese stainless steel, which is harder than 304 stainless steel, high carbon and low nickel.

　　7. The composition of 304 stainless steel and 201 stainless steel is different (mainly distinguish 201 and 304 stainless steel from the aspects of carbon, manganese, nickel and chromium). Steel grade Carbon (C) Silicon (Si) Manganese (Mn) Phosphorus (P) Sulfur (S) Chromium (Cr) Nickel (Ni) Molybdenum (Mo) Copper (Cu).
