|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|
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||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.|
