Product Description

Cold Drawn Hydraulic Cylinder Tube , Seamless Stainless Steel Tube

 

 

hydraulic cylinder tube

Detailed Product  Description

Based on the optimized cold drawn process and reliable raw material source, we significantly reduce

 the stock margin for the honed tubes and increase dimensional accuracy of inside and outside diameters.

 By cold drawing, it improves mechanical properties which can provide a wall thickness reductions of up to 

30%, and leading to significant component weight reduction

  11.   Tube Ends
                  Tube ends shall cut square to the  tube axis and be free from excessive burrs. 
             Both ends protected with Plastic caps.

              As the result of stress relieved annealing after the final drawing, residual stresses are reduced, 

forming within defined limits is made possible, and dimensional changes during/after machining are

 minimized.
