304 stainless steel and 201 stainless steel difference:

1, different chemical composition: the general stainless steel are based on iron, carbon with nickel, chromium, manganese and other metal elements, so that it produces anti-rust properties, 304 stainless steel with nickel, chromium and 201 stainless steel than more manganese ratio 201 stainless steel less.

2, chemical properties: Ni-Cr metal mainly from the role of corrosion, 304 stainless steel with more nickel-chromium, corrosion resistance than 201 stainless steel.

3, physical properties: 304 stainless steel toughness, 201 stainless steel lack of toughness, stretching process requires a lot of force, and easy to crack.

4, safety performance: 201 stainless steel contains high manganese, harmful to the human nervous system, 304 stainless steel safety food grade material, the current food grade stainless steel are 304 stainless steel and above.

5, the price: 304 stainless steel nickel, chromium and more, good corrosion resistance, expensive, 201 stainless steel prices low,

6, the scope of application: 304 stainless steel corrosion resistance, and more for outdoor construction, 201 stainless steel acid, alkali performance, and more for interior decoration pipe, industrial pipe.

304 stainless steel Features:

304 stainless steel with nickel, chromium and more, good corrosion resistance, high toughness, the price is expensive! Used for anti-corrosion building.
