Features Of 201 Stainless Steel And 304 Stainless Stee

1. Specifications: The commonly used stainless steel plates are divided into two types, 201 and 304, which are actually different in composition. 304 is of better quality, but the price is more expensive, and 201 is worse.

2. 201 is the Ni-section steel grade, which is an alternative to 301 steel. After cold processing, it has magnetism and is used in railway vehicles.

3. 304 is the most widely used stainless steel and heat-resistant steel. Used in food production equipment, general chemical equipment, nuclear energy, etc.

4. 201 has high manganese content, the surface is very bright with dark and bright, and high manganese content is easy to rust. 304 contains more chromium, the surface is matte, does not rust, and the two are compared together. 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 304.

5. The difference between 201 and 304 is the problem of nickel. Moreover, the price of 304 is now more expensive, generally close to 50,000 yuan a ton, but 304 can at least guarantee that it will not rust during use. (You can experiment with potions)

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