ISO H8 Cylinder tube is a cold-drawn steel tube, steel grade ST52 , in accordance with DIN 2391 HONED with ISO-tolerance range H8 on the internal diameter. Basic material for manufacturing welded hydraulic cylinders particularly suitable for the industrial, mobile and special applications sector.
Honing process Of H8 Cylinder Tube
* machining the internal surface of the tube to a precise diameter and surface finish
* using a honing stone to remove material and achieve the desired surface finish
* Resulting in a smooth , cylindrical internal surface with a surface finish of Ra 0.2 – 0.4um ( micro – inches)
