Delivery Condition
| Designation | Symbol | Description |
| 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 | 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. |
