Product Description
Product Description
Automobile and motorcycle precision pipe is mainly used in processing,production of automobile and motorcycle
shock absorber,bushing,oilcylinder,needle bearings and other parts.

The hydraulic cylinder tube is the main part of the hydraulic cylinder.The inner hole of the hydraulic cylinder tube 
 processed by boring,reaming,rolling or honing.By these process can ensure the piston,sealing elements 
and the support elements move smoothly,then ensure the sealing effect and reduce the abrasion.The hydraulic cylinder 
tube will bear big pressure,so need high strength and stiffness.

Heat Treatment/      Delivery Condition
  1. Cold finished (hard)   BK(+C)
Tubes do not undergo heat treatment following the final cold forming and, thus, have a rather high resistance to deformation
  1. Cold finished (soft)    BKW(+LC)
The final heat treatment is followed by cold drawing involving limited deformation. Appropriate further processing allows a certain degree of cold forming (e.g. bending, expanding)
  1. Cold finished and stress-relieved annealing BKS(+SR)
Heat treatment is applied following the last cold forming process. Subject to appropriate processing conditions, the increase in the residual stresses involved enables both forming and machining to a certain degree.
  1. Annealed    GBK(+A)
The last Cold forming process is followed by annealing in a controlled atmosphere.
  1. Normalized   NBK (+N)
The last cold forming process is followed by annealing above the upper transformation point in a controlled atmosphere.
