DIN2391 Cold Drawn Seamless Tube in High Precision
Synopsis of Process Routing: quality carbon steel → cold drawing → 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 capping 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.
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.
