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.
