There are many models of stainless steel, each with slightly different effects, and it is necessary to distinguish them clearly in advance. What are the differences between 304 and 201 stainless steel.

What are the differences between 304 and 201 stainless steel

1. Composition: 304 steel contains 19 chromium and 10 nickel, while 201 steel contains 17 chromium and 5 nickel.

2. Corrosion resistance and acid resistance: Due to different nickel contents, the corrosion resistance of 201 steel is not as good as that of 304 steel, and the acid and alkaline resistance of 201 steel is not as good as that of 304 steel.

3. Color: Because 201 steel contains manganese and 304 steel does not, the surface of 201 steel is very bright, while 304 steel contains chromium and has a dull surface.

4. Compression resistance: Due to the higher carbon content of 201 steel compared to 304 steel, 201 steel is harder and more brittle than 304 steel. 304 steel has good toughness. The scratches on the surface of 201 steel are usually more obvious, while the scratches on 304 steel are not obvious.

5. Specification: Currently, commonly used steel materials are mainly divided into 201 and 304. However, due to different elements, the quality of 304 steel is good, but the price is relatively high, while the quality of 201 steel is relatively poor. 04 is imported steel, 201 is domestic steel.
