Cold-drawn or cold-rolled precision seamless steel tubes (GB3639-2000) are high-precision steel tubes specifically designed for mechanical structures and hydraulic systems. These tubes are manufactured using cold-drawing or cold-rolling processes, which ensure exceptional dimensional accuracy and a smooth surface finish. As a cutting-edge energy-saving product, high-precision cold-drawn steel tubes have gained widespread application due to their ability to reduce material consumption, improve machining efficiency, and lower energy usage.
The primary materials used in the production of these precision tubes include St35, St37.4 (10#), St45 (20#), St55 (35#), Ck45 (45#), and St52 (16Mn), mainly sourced from Shanghai Baosteel. The mechanical properties of the tubes produced by the Precision Pipe Department are outstanding, offering excellent strength, toughness, and resistance to high pressure and impact. This makes them ideal for use in hydraulic machinery, automotive components, and other demanding industrial applications.
These steel tubes can be cold-formed at any angle without cracking, allowing for expansion, flattening, or bending as required. Their versatility makes them suitable for industries that require complex deformation processes. Whether for automotive, construction, or manufacturing sectors, cold-drawn precision seamless steel tubes offer reliable performance and long-term durability.
With continuous advancements in manufacturing technology, these tubes continue to play a vital role in modern engineering solutions. Their superior quality and adaptability make them an essential component in a wide range of applications.
