Many customers can't distinguish 201 stainless steel plate and 304 stainless steel plate when purchasing. In fact, it is relatively simple to distinguish between these two kinds of steel plates.
1. Specifications: There are many types of steel plates on the market. 201 and 304 are the two most commonly used types. However, the composition of these two types of steel plates is very different. The quality of 304 is better than that of 201, and the price is naturally more expensive. Generally, 304 is imported steel plate, and 201 is domestic steel plate.
2. 201 steel plate is a Ni-section steel, which is an alternative to 301 steel plate. It has certain magnetic properties after cold working, which is more suitable for processing vehicles.
3. The use of 304 steel plate is very extensive. It is easy to see it in life and production, and it is used in food production equipment, general chemical equipment, etc.
4. The manganese content in 201 steel plate material is relatively high, although the surface of the material is bright but with dark light, but this kind of steel plate is more prone to rust. The 304 steel plate material contains a lot of chromium, and the surface of the steel plate is matte, which is not easy to rust. Due to the difference in corrosion resistance, the price of the two is very different.
5. Another difference between 201 and 304 stainless steel plates is that the amount of nickel contained in the material is different. The 201 steel plate itself is a high manganese stainless steel, the hardness of the material is relatively large, and the carbon content is high, but the nickel content is low.
A relatively simple way for customers to identify 304 and 201 steel plates when purchasing is to observe the surface of the steel plates. The surface of 304 steel plates has good gloss and will feel smooth when touched by hand, while the surface of 201 steel plates is dark and can be touched by hand. There will be roughness.
