Our company boasts advanced cold drawing seamless tube production equipment and highly skilled employees, capable of customizing various specifications and materials of cold drawn seamless steel tubes for you. Our products are characterized by high precision, tight tolerances, and timely delivery. Welcome to place your order. Materials include: 10#, 20#, 45#, 16Mn, 20Cr, 40Cr, 15CrMo, 35CrMo, etc. Standard: GB/T3639-2009. Applications: suitable for mechanical structures, hydraulic equipment, cylinders, drums, parts processing, automotive (motorcycle) accessories, and diamond thin-walled drill bits. Production range and tolerances: 10-108mm x 1-14mm, tolerances of 2-10 microns.
Product Features: Our cold drawn seamless steel tubes are free from surface defects such as blisters, scratches, cracks, and scaling. Both inner and outer surfaces are bright and smooth, surpassing those of regular cold drawn tubes significantly. The tolerance is as small as 0.02mm. Thus, they are commonly used in fields with high demands for precision and surface finish to enhance product quality and reduce processing costs.
