201stainless steel strip J1 J2 J3 J4 J5

详情

Our company has its own rolling annealing plant, with 10 annealing production lines. Output of 201 stainless steel rolls over 10,000 tons per month, BA surface finish, HL, polish, matte, can be done. The product line has different grades of materials, such as 201J1, J2, J3, J4 and J5.

J1: Slightly more carbon than J4 and less copper. Its processing property is inferior to J4 material. Suitable for ordinary shallow drawing and large Angle deep drawing products, such as decorative board, bathroom products, sinks, product pipes, etc

J2, J5: Simple processing is conducive to decorative pipe, because of high hardness (all above 96°) and beautiful polishing, but prone to burst when used in square pipe or curved pipe (90°). In the flat plate, because of the high hardness, the surface of the panel is more beautiful, matte, polishing, color plating and other surface treatment is acceptable. But the biggest problem is bending, bending is easy to break, planing is easy to burst, so the ductility is not good

J3: High carbon, low chromium and low copper, but because of its high carbon content, low copper content, the material is slightly hard, so it is not suitable for slightly stronger bending. Compared with 201 stainless steel J1 material, the ductility is not so good, and it is more prone to rust in the same environment.
 

In the narrow band sector, 201 stainless steel J3 material has a more developed appearance to meet pipe manufacturers' requirements for corrosion resistance and deformation. Because it can reduce the cost of raw materials for pipe manufacturers, it is sought after by pipe manufacturers in the narrow band field.
