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.
