1. Specification: The commonly used stainless steel sheets are divided into model 201 and 304. Actually, the composition is different. 304 is of better quality, but the price is more expensive than 201. 304 is imported stainless steel plate and 201 is domestic stainless steel plate.

2. 201 is composed of 17Cr-4.5Ni-6Mn-N, which is a substitute steel for saving Ni and 301 steel. It has magnetism after cold processing and is used in railway vehicles.

3. 304, consisting of 18Cr-9Ni, is the most widely used stainless steel and heat-resistant steel. Used in food production equipment, chemical equipment, nuclear energy and so on.

4. 201 has a high manganese content, a bright surface with dark and bright, which is easy to rust. 304 contains more chromium and the surface is matte and rust-free. It is easy to compare them. The most important thing is that the corrosion resistance of 201 is very poor, so the price is much cheaper. That is because 201 contains low nickel, so the price is lower than 304 and the corrosion resistance is not as good as 304.

5. Different compositions (mainly from stainless steel 201 and 304 with carbon, manganese, nickel and chromium carbon (C) silicon (Mn) phosphorus (S) chromium.

We offten use SS 304 in our MIM items to promise quality.
