EN10305/DIN Series precision steel tubes

Synopsis of Process Routing:queality 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.
