Product Desciption

The honing/ roller burnished seamless steel hydraulic tubing, hydraulic steel pipe and hydraulic cylinder tube is cold draw both inside and out, then is given tempering treatment with a tensile strength of up to 520N / mm2 or more. Improved Inside honing or roller burnishing equipment guarantee the H7, H8 diameter tolerance.It helps to extend the life of the cylinder, and reduces the wear of the seal. The honing/skived and roller burnished seamless steel hydraulic tubing, hydraulic steel pipe and hydraulic cylinder tube steel grade include EN 1.0580, E355, STKM13C, STKM13A and DIN ST52.
Our factory has advance production lines for Inside honing, roller burnishing production.
