1026 Steel honed tube is also called hydraulic honed barrel,As one of the leading hydraulic cylinder honed tube suppliers and manufacturers,Wuxi YUTONG has been supplying and exporting honed tube and honed cylinder barrel for almost 20 years. We produce honed steel tubes and skived roller burnished tubes used for hydraulic cylinder or pneumatic cylinder with high quality & good prices.Imperial sizes & metric sizes available.
Heat Treatment Delivery Condition
Cold finished (hard) BK(+C)
Tubes do not undergo heat treatment following the final cold forming and, thus, have a rather high resistance to deformation
Cold finished (soft) BKW(+LC)
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 annealing BKS(+SR)
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(+A)
The last Cold forming process is followed by annealing in a controlled atmosphere.
Normalized NBK(+N)
The last cold forming process is followed by annealing above the upper transformation point in a controlled atmosphere.
