Difference between 201 and 304 Stainless Steel

The main difference between 201 and 304 stainless steel lies in nickel content and corrosion resistance. SS201 has low nickel, cost-effective for indoor decoration, indoor handrails and security frames, but not suitable for coastal salt-spray environments. SS304 contains more nickel, offering better rust resistance. It works well both indoors and outdoors and is widely used in most construction projects.
