Cold Drawn Cylinder Tube

Tubes are homogeneous and own superior mechanical properties after cold drawn and stress relief annealing. For higher I.D. surface requirement, I.D. of tubes are further honed by precise honing machines which produced and designed by Costar to match the condition, roughness and tolerance of designated standard.

Costar also has adequate stock in standard sizes. Besides, special specification, material and size are available upon request to satisfy all customers’ needs.
