Round Cold Draw Seamless Mechanical Tubing

• DIN highly accurate, cold drawn and bright seamless steel tube is used as the tube to be phosphated. The phosphated is realized with the imported chemical fluid to form a black film. The antirust oil is absorbed by means of the micropore on the film to prevent from the rust. The caps are covered at two ends of tube to prevent from the dust.
• 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.
• The color of NBK tube is Bright Black. Color is homogeneously distributed on the tube surface. The tube has good property of antirust.
