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

              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.
