What are the differences between 304 stainless steel plate vs 201? The following editor of Asiametal stainless steel will introduce to you:
1. Specifications: The commonly used stainless steel plates are divided into two types: 201 and 304. In fact, they are different in composition. 304 has better quality, but the price is more expensive, and 201 is worse. 304 is imported stainless steel plate, and 201 is domestic stainless steel plate.
2. Useful steels are different: 201 is composed of 17Cr-4.5Ni-6Mn-N, which is a Ni-saving steel grade and an alternative to 301 steel. After cold processing, it has magnetism and is used in railway vehicles.
3. The application is different: 304 is composed of 18Cr-9Ni, which is a 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 and bright, high manganese content is easy to rust. 304 contains more chromium, the surface is matte and does not rust. The two are compared together. The 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 304.
5. The composition is different: (mainly from carbon, manganese, nickel, and chromium to distinguish 201 and 304 stainless steel) Steel grade carbon (C) silicon (Si) manganese (Mn) phosphorus (P) sulfur (S) ) Chromium (Cr) Nickel (Ni) Molybdenum (Mo) Copper (Cu).
