    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.
