Recently, many people are asking about 201 stainless steel coil, which is also 201, but the price of J1-J5 is different.
In stock attached:
J1: The carbon content is slightly higher than J4 and the copper content is lower than J4. Its processing performance is not as good as J4 material. It is suitable for ordinary shallow deep drawing and deep drawing products with large angles, such as decorative panels, bathroom products, sinks, product pipes, etc. .
J2, J5: Simple processing is good for decorative pipes, because of high hardness (both above 96°) and beautiful polishing, but it is easy to burst when used in square pipes or bent pipes (90°).
J3: High carbon, low chromium and low copper, but because of its high carbon content and low copper content, the material is slightly harder, so it is not suitable for bending with a slightly stronger strength. Compared with 201 stainless steel J1 material, the ductility is not so good, and it is easier to rust in the same environment.
J4: J4 material is a higher-end variety in the J series of 201 stainless steel. It is suitable for the small-angle type of deep-drawn products. Most of the products that require deep-drawing and salt spray tests will choose it. Such as sinks, kitchen utensils, bathroom products, kettles, thermos cups, door hinges, pots, etc.
Therefore, what level to choose needs to be chosen according to the actual situation. I hope my introduction is helpful to you. We have been engaged in the steel industry for more than ten years and have long-term cooperation with foreign customers. Looking forward to your consultation.
