Delivery condition:

 
DesignationSymbolDescription
Cold finished (hard)BKTubes do not undergo heat treatment following the final cold forming and, thus, have a rather high resistance to deformation.
Cold finished (soft)BKWThe 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-relievedBKSHeat 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.
AnnealedGBKThe last cold forming process is followed by annealing in a controlled atmosphere.
NormalizedNBKThe last cold forming process is followed by annealing above the upper transformation point in a controlled atmosphere.
