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.
