We are committed to providing one-stop service for steel pipe products to customers around the world.
Automobile transmission shaft is one of the main components of automobile transmission system.
The steel pipe for transmission shaft is a special thinwall thicknes straight seam welded pipe. In order to ensure stable and reliable torque transmission.
There is strict technical requirements on these drive shaft tube:
1. high strength yield
2. strict precision on dimension
3. The most optima Manufacturing process - anneal the tube blank before cold drawing to improve the metallographic structure of the pipe and weld, reduce the strength and improve the plasticity. Then straightening, pickling, phosphating, saponification, cold drawing.
