    Hydraulic Precision Cold Draw Seamless Tube DIN2391 ST52.4 and St37.4

     

    Final supply conditions:
     
    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.
