Cold Drawn Seamless Hydraulic Cylinder Honed Tubes

EN 10305-1 E355 Seamless Carbon Steel Hydraulic Cylinder Honed Tube

The similar steel tubes as DIN2391 St52.3 cold drawn precision tubes.

The steel tubes produced from cold drawn steel tubing with honing and skiving,

roller burnished in the inner and outer steel tubes surface to promise the high

surface roughness and tolerance for application of hydraulic cylinders,hydraulic jack,

telescope cylinders,and precision cylinder shaft rods.
