Stainless steel 201 and 304 two models difference

1, the actual composition is different, 304 better quality, 201 worse.

2, their corrosion resistance is different, 201 corrosion resistance is slightly poor, so the price will be much cheaper. Because 201 contains low nickel, the price is lower than that of 304, so the corrosion resistance is not as good as that of 304.

3,201 is higher manganese, bright surface with dark, bright, high manganese rust; 304 contains more chromium, the surface is matte, no rust. .

4, stainless steel is not easy to rust because the formation of chromium oxide on the surface of the steel body can protect the steel body, so the difference between 201 and 304 is also a nickel problem. 201 material belongs to high manganese stainless steel 304 hardness than high carbon and low nickel.

5, their composition is different, mainly from the carbon, manganese, nickel, chromium containing several aspects to distinguish 201 and 304 stainless steel

6, its fatigue resistance, 201 greater hardness, toughness than 304, or 304 fatigue better.

7,201 is composed of 17Cr-4.5Ni-6Mn-N, is a Ni-saving steel, is 301 steel alternative steel; 304 composition is 18Cr-9Ni, is widely used stainless steel, heat-resistant steel.
