J2, J5: suitable for decorative tube. Simple decorative tube is good, because the hardness is high (above 96°), polished tube is more beautiful, but the square tube or in the bend (90°) is prone to burst due to its poor malleability.
J3: high carbon low chromium low copper. But because of its high carbon content and less copper content, the material is slightly harder, so it does not adapt to the bending of slightly larger strength. 201-J3 is also less malleable than 201-J1 and is more prone to rust in the same environment. J3 is suitable for decorative tubes. 
J4: is the higher-end variety of J series, which is suitable for the small-angle type of deep-drawn products. Most of the products that require deep stretching and salt spray test will choose it. For example, sink, kitchenware, bathroom products, kettle, thermos, hinge, cooker, etc.
