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-rellevedBKSHeat treatment is applled 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
