    Hydraulic Cylinder Honed Tube , Mechanical Tubing Corrosion Resistant

    Hydraulic Cylinder Honed Tube , Mechanical Tubing Corrosion Resistant


    Detailed Product Description

    Cold drawn seamless tubes for mechanical and automotive components have the precise tolerance

    as per design purpose, especially for the small outside diameter and heavy wall tube which is beyond

    the limit of the welded tube size range. By cold drawing, the mechanical properties get increased.

    Delivery Condition

    Delivery Condition

    +C

    No heat treatment after

    the final cold drawing process

    BK

    Tubes do not undergo heat treatment

    following the final cold forming and,

    thus, have a rather high resistance

    to deformation

    +LC

    After the final heat treatment

    there’s a suitable drawing pass

    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)

    +SR

    After the final cold drawing

    process there’s a stress relief

    heat treatment in controlled

    atmosphere

    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

    +A

    After the cold drawing process the

    tubes are annealed in

    a controlled atmosphere

    GBK

    The last cold forming process

    is followed by a nnealing in

    a controlled atmosphere

    +N

    After the final cold drawing

    operation the tubes are normalized

    in a controlled atmosphere

    NBK

    The last cold forming process

    is followed by annealing above the

    upper transformation point in a

    controlled atmosphere
