AISI 304, SS316L, Ss347 H8,H9 Hydraulic Cylinder Honed Tube
Honed Tube is well known as hydraulic cylinder tube in industries. Honed Tubes, Skived & Roller Burnished Tubes are the most important material of manufacturing hydraulic cylinders.
As one of the leading hydraulic cylinder honing tubes suppliers and manufacturers, Kingmetal has been supplying and exporting honed steel tube 15+years.
We produce honed steel tubes and skived roller burnished tubes used for hydraulic cylinder or pneumatic cylinder with high quality with better prices.

Delivery Conditions
The tubes shall be manufactured from cold drawn or cold rolled processes. The tubes shall be supplied in one of the delivery conditions as follows:
| Designation | Symbol | Description |
| Cold finished (hard) | BK | Tubes do not undergo heat treatment following the final cold forming and thus, have a rather high resistance to deformation. |
| Cold finished (soft) | BKW | The final heat treatment is followed by cold drawing involving limited deformation. Appropriate further processing allows a certain degree of cold forming (e.g. bending, expanding). |
| Cold finished and stress-relieved | BKS | Heat treatment is applied following the last cold forming process. Subject to appropriate processing conditions, the increase in the residual stresses involved enables both forming and machining to a certain degree. |
| Annealed | GBK | The last cold forming process is followed by annealing in a controlled atmosphere. |
| Normalized | NBK | The last cold forming process is followed by annealing above the upper transformation point in a controlled atmosphere. |
