What is the difference between 201 stainless steel and 304?

2022-06-21

1. Different colors: 201 stainless steel has a dull surface color, and 304 stainless steel has a smooth and bright surface. The corrosion resistance, acid and alkali resistance of 201 stainless steel are not as good as 304 stainless steel. 304 stainless steel has an absolute advantage in performance, so its coverage is wider than 201 stainless steel. In addition, 304 stainless steel is more expensive than 201 stainless steel.

2. Difference in color plating: Vacuum electroplating is better than water electroplating, but both color plating methods will first remove the protective film of stainless steel. It is recommended to use 304 stainless steel for electroplating color stainless steel pipes.

3. Performance difference: It should be noted that due to the difference in the content of chromium and nickel and the difference in carbon content, the 304 stainless steel pipe is a bit softer than the 201 stainless steel pipe, and the 304 stainless steel has better corrosion resistance.
