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.
