    Final supply conditions


    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.

    Applications


    Zinc coated precision steel tubes (galvanized tubes) are destined for hydraulic and pneumatic pressure distribution (so called HPL tubes),

    production of automobile components, utility vehicles as well as for production of machine products such as fittings and joints.

    Cold drawn precision tubes are used as the semi-finished product and they are made from rolled seamless tubes.

    Precision tubes HPL types are made from carbon and alloyed steel.


    Application areas:

    Automotive, military, railway industry, with high requirement of the tubes brightness, cleanness, antirust, and antisepsis.
