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.
