Due to the lack of anneal processing, material itself can be more hard. Generally,it won’t undertake mechanical processing ,only undertake simple processing. And the performance of the product is poorer.Therefore, cold rolled plate is usually annealed to increase its practicability.There is a kind of material is through the plate further processing of the steel plate, so that the steel plate will not produce scale, practical better, in the application of the product has been widely praised.

After the quality of plank and dimension reached standard requirement, pass annealing processing again, the performance of such cold rolled sheet and practical it is very good, and more and more reflect its outstanding also in many domain, especially home appliance kind product, already cannot leave this kind of plank.Among the industrial products, the practical application of this kind of pipe material has become one of the mainstream products.
