Generally in stainless steel manufacturers will have two kinds of materials, 201 stainless steel and 304 stainless steel.Some manufacturers can produce 304 stainless steel, some can produce 201 stainless steel, some manufacturers can produce two kinds of stainless steel profiles.But in the eyes of many consumers can not distinguish 304 stainless steel and 201 stainless steel, today we share with you the difference between the two types of steel! The difference between 304 stainless steel and 201 stainless steel: 1, chemical composition is different: general stainless steel is in iron, carbon on the basis of nickel, chromium, manganese and other metal elements, to produce rust resistance, 304 stainless steel containing nickel, chromium elements than 201 stainless steel, manganese element than 201 stainless steel less. 2, chemical properties: nickel-chromium metal mainly plays the role of corrosion resistance, 304 stainless steel containing nickel-chromium, corrosion resistance than 201 stainless steel. 3, physical properties: 304 stainless steel toughness, 201 stainless steel toughness, tensile process needs 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 edible grade material, the current edible grade of stainless steel are 304 stainless steel and above the level. 5, price: 304 stainless steel nickel, chromium, good corrosion resistance, the price is expensive, 201 stainless steel price is low, 6, scope of application: 304 stainless steel corrosion resistance is good, mostly used in outdoor buildings, 201 stainless steel acid resistance, alkali resistance is good, mostly used in interior decoration pipe, industrial pipe. 304 stainless steel features: 304 stainless steel containing nickel, chromium, good corrosion resistance, high toughness, expensive!It is mainly used in anti-corrosion buildings. 201 Stainless steel features: 201 stainless steel contains less nickel, chromium, corrosion resistance is weak, manganese, acid and alkali resistance is good, cheap!It is mainly used for decoration pipe and industrial pipe. Summary: 304 stainless steel and 201 stainless steel is the biggest difference between the nickel, chromium, manganese composition is different, so corrosion resistance and toughness will be different, chemical composition determines physical properties and chemical properties.
So please choose 304 stainless steel products when you have the choice since it is good for your health.
