304 have what difference with the stainless steel data of 201

The biggest difference above raw material of stainless steel cistern is cent is 304 stainless steel and the cent of 201 stainless steel namely, product of 229 yuan stainless steel cistern is 201 stainless steel at all, neither one breaks rules, some businessmen still do not indicate raw material, to sell goods more, a few brother are experienced bought with respect to gain, do not have at all originally, because 201 stainless steel are worth so much money only.

304 stainless steel board
304 and 201 between the chemical composition that the biggest difference is them namely is different. The quantity containing carbon that the difference of rolled steel and iron is rolled steel namely wants than iron tall, so rolled steel wants than iron hardness tall. Stainless steel is a kind of rolled steel, stainless steel does not become rusty, be the metal such as nickel, chromic, manganese was added on the foundation of iron, carbon, make it produces antirust function.
Normally 304 stainless steel contain nickel quantity to be 8, the quantity that contain chromium is 18; And 201 stainless steel contain nickel quantity photograph is lower than wanting a lot of, want 0.8-1 only order about, the quantity that contain chromium is 13-15 order about. Because of nickel chromic content different, so the physical sex plastid in them also is different now.

201 cistern are rusty
1, nickel chromic metal is first rose to fight corrode the effect, nickel chromic content is low, natural fight corrode a function normally, and cistern is in wet environment in, and the soda acid content such as spirit of smeary, salt, catharsis metropolis bring into contact with, 201 stainless steel are not so good as cistern, although short-term do not look to go out have what change, use for a long time nevertheless, cistern surface pales, lose luster, produce rubiginous mark.
2, endurance not as good as 304 stainless steel, the cell body of cistern is drawing of an organic whole normally and into, craft cistern is outer, the stainless steel ply of a 1.2mm board pass primary drawing, quench and 2 class drawing henceforth, formed the cell body of 20cm deepness, ply also turns into between 0.8-1mm.
Endurance of 201 stainless steel is insufficient, need greater power in drawing process, and quench too much, affected stainless steel function of whole, and simple also rip.

The aubergine with toxic manganese
3, 201 stainless steel contain manganese taller, harmful to human body. Present edible class stainless steel is 304 stainless steel and above grade, because 201 stainless steel contain manganese the volume is high, manganese is right of human body neurological have intense noxiousness, the country already checked now the raw material of basin of gourd ladle of the bowl that it is boiler, was thought of everybody healthy, especially the full-dress container with latter source of this kind of removed food, still be not to use 201 stainless steel had better.
