The hot and cold drawing (rolling) state of the delivery state of the stainless steel precision tube

Hot and cold drawn (rolled) state of the delivery state of stainless steel precision tubes. The raw material of stainless steel precision tubes is cold-drawn, cold-rolled and other cold-formed steel materials, and the state of delivery directly without any heat treatment is called cold-drawn or cold-rolled state. Compared with the hot-rolled (forged) state, the cold-drawn (rolled) state of the steel has high dimensional accuracy, good surface quality, low surface roughness, and higher mechanical properties. Because of the cold-drawn (rolled) state of delivery of steel The surface is not covered by oxide scale, and there is a large internal stress, which is easily corroded or rusted. Therefore, the packaging, storage and transportation of cold-drawn (rolled) steel have strict requirements, and generally need to be kept in a warehouse. And attention should be paid to the temperature and humidity control in the stainless steel precision tube warehouse.
