The difference of SS304 and SS201

- Jun 24, 2020-

"The surface of 201 stainless steel is dull, and the surface of 304 stainless steel is smooth and bright. The corrosion resistance, acid and alkali resistance of 201 stainless steel are not as good as 304 stainless steel. Because of the absolute advantage in performance, 304 stainless steel has a wider coverage than 201 stainless steel. In addition 304 stainless steel is more expensive than 201 stainless steel.


1.Performance difference

304 stainless steel and 201 stainless steel have different chromium and nickel content and different carbon content. 304 stainless steel is softer than 301 stainless steel, but the corrosion resistance of 304 stainless steel is better.


2.Application range difference

304 stainless steel has good corrosion resistance and high temperature resistance, and can be used in bathroom, kitchen and coastal wet areas; 201 stainless steel is mainly used in dry areas or decorative areas!


3.Color difference

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