Heat Treatment/      Delivery Condition	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 limited deformation. Appropriate further processing allows a certain degree of cold forming (e.g. bending, expanding) Cold finished and stress-relieved annealing BKS(+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. Annealed    GBK(+A) The last Cold forming process is followed by annealing in a controlled atmosphere. Normalized   NBK(+N) The last cold forming process is followed by annealing above the upper transformation point in a controlled atmosphere.
