Cold drawn steel tube is a type of steel tube material processed through cold drawing or hot rolling. Due to its advantages such as oxide-free inner and outer walls, high precision, high luster, ease of cold bending without deformation, and no cracks upon flattening, it is primarily used in the production of pneumatic or hydraulic components, such as cylinders, which can be seamless or welded. It is widely applied in industries such as shipping, telecommunications, petrochemicals, construction, aerospace, and machinery.
