Stainless steel 201 304 difference

1. Specifications: The commonly used stainless steel plates are divided into two types: 201 and 304, which are actually different in composition.

The quality of 304 is better, but the price is expensive, and the 201 stainless steel plate is worse. 304 is imported stainless steel plate, 201 is domestic stainless steel plate.

2. 201 is a Ni steel grade and an alternative to 301 steel. It is magnetic after cold working 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 is high in manganese, the surface is very bright with dark and bright, and the high manganese content is easy to rust. 304 contains more chromium, and the surface is matte and does not rust. The two can be 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. And because 201 contains low nickel, 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 nickel content. Moreover, the price of 304 is relatively expensive now, generally close to 50,000 a ton, but 304 can at least guarantee that it will not rust during use. (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. The 201 material belongs to high manganese stainless steel, which is higher in hardness than 304, and has high carbon and low nickel.
