E355 ST52 Seamless Cold Rolled Honing H8 Tolerance Hydraulic Cylinder Pipe For Piston Tube
Honing tube is a high-precision seamless steel tube, which is processed by grinding and rolling. It has the advantages of no oxide layer on the inner surface, no leakage under high pressure, high precision, high finish, cold bending, and no deformation when expanding. It is flat and crack-free. It is widely used in hydraulic cylinder systems, automotive parts, boiler equipment and mechanical performance industries.
