304 stainless steel and 201 stainless steel difference

September 29, 2021

304 stainless steel and 201 stainless steel difference:

1, the chemical composition is different: general stainless steel is in iron, carbon based on nickel, chromium, manganese and other metal elements, so that its rust resistance, 304 stainless steel nickel, chromium than 201 stainless steel, manganese than 201 stainless steel.

2, chemical properties: nickel chromium metal mainly plays a role in corrosion resistance, 304 stainless steel nickel chromium, corrosion resistance is stronger than 201 stainless steel.

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

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

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

6, scope of application: 304 stainless steel corrosion resistance, used for outdoor buildings, 201 stainless steel acid resistance, alkali resistance is good, used for indoor decoration pipe, industrial pipe.
