Cold Drawn and Cold Rolled Seamless Precision Steel Tube

Synopsis of Process Routing

Quality carbon steel-cold drawn-heat treatment without oxidization(NBK status)-nondestructive testing.
In the wall honing and inside flushing under the high pressure -Antirust oiling outside surface - plastic capping on both ends.

Main Features

high precision, excellent brightness, no oxidization on the outer and inner walls after heat treatment, high cleanness of inside wall. The steel tube is able to withstand high pressure. No deformation after cold bending, no crack after flaring and flattening.The complicated geometrical forming and machining can be realized. Color of tube: gray with white

Main Application

To be used in hydraulic system, automobile and in the occasion where the high precision, brightness cleanness and mechanical properties of the tube are required.
