Cold Rolled

Main Applicationused in automotive industry, and in the occasion where the high accuracy, brightness, cleanness of the tube are required.

Main Featuresinner and outer walls of tube have high accuracy, excellent brightness, no oxidization after heat treatment, and high cleanness inside tube. The steel tube is able to stand 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: bright white, with high metallic luster.

Synopsis of Process RoutingQuality carbon steel cold rolling bright heat treatment without oxidization (NBK status) nondestructive testingin the wall honing and inside flushing under the high pressure antirust oiling outside surface plastic capping on both ends.

Main Characteristics: No oxidation layer on the outer and inner walls;No leakage under high pressure; High precision; High cleanness and excellent brightness; No distortion after cold bending; No crack under flaring and flattening;
