The difference between 201 stainless steel and 304 stainless steel:

1. The composition is different:

201 stainless steel contains 15% chromium and 5% nickel. 201 stainless steel is an alternative to 301 steel. Standard 304 stainless steel with 18% chromium and 9% nickel.

2. Different corrosion resistance:

201 is high in manganese, the surface is very bright with dark and bright, and high in manganese is easy to rust. 304 contains more chromium, the surface is matte and does not rust. Stainless steel is not easy to rust because the formation of chromium-rich oxides on the surface of the steel body protects the steel body.

3. The main applications are different:

201 stainless steel has the characteristics of certain acid and alkali resistance, high density, no bubbles and no pinholes in polishing. Mainly used for decorative pipes, industrial pipes, and some shallow-stretched products. 304 stainless steel has the characteristics of good processing performance and high toughness, and is widely used in industrial and furniture decoration industries and food and medical industries.
