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
