applications:
precision steel tubes 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.
features of DIN 2391 Cold drawn seamless steel tube,ST-52 Seamless Precision steel tubes
high accuracy, outstanding brightness, no oxidization on the outer and inner walls after heat treatment, high cleanness inside wall. The steel tube has the ability to stand high pressure. No contortion after cold bending, no crack after flaring and flattening. The complex geometrical forming and machining can be understood. Color of tube: gray with white.
