Delivery Condition

DesignationSymbolDescription
Cold finished (hard)BK ( +C )Tubes do not undergo heat treatment following the final cold forming and, thus, have a rather high resistance to deformation
Cold finished (Soft)BKW ( +LC )The final heat treatment is followed by cold drawing involving deformation. Appropriate further processing allows a certain degree of cold forming (e.g. bending, expanding)
Cold finished and stress-relievedBKS ( +SR )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.
AnnealedGBK ( +A )The last Cold forming process is followed by annealing in a controlled atmosphere.
NormalizedNBK ( +N )The last cold forming process is followed by annealing above the upper transformation point in a controlled atmosphere.
