Size range of precision Cold-rolled Seamless Tube with Bright Anneal:
| size | Min | Max |
| OD | 12mm | 80mm |
| WT | 0.5mm | 10mm |
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.
Quality carbon steel、cold -rolled 、 bright heat treatment without oxidization (NBK status) 、 nondestructive testing、 in the wall honing and inside flushing under the high pressure、 antirust oiling outside surface、plastic caping on both ends.
Main Features：high accuracy, excellent brightness, no oxidization on the outer and inner walls after heat treatment, high cleanness inside wall. 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: gray with white.
