    Specification


    Designation

    Symbol

    Description

    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

    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.

    DIN 2391 Precision seamless steel tube


    This Standard applies to seamless precision steel tubes; and, in compliance with ISO/DIS 3304, those tube dimensions have een selectied from the range of manufactura le tu e dimensions which are mainly used as design elements

    If tubes having the tolerances and are produced according to the technical conditions of deivery as specified in this Standard are to e used as pipelines, then the dimensions specified in DIN 2448 may from time to time be used. These tubes must be ordered according to quality grade C.
