Final supply conditions:
Designation | Symbol | Description |
Cold finished (hard) | BK | 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 | 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 | The last cold forming process is followed by annealing in a controlled atmosphere. |
Normalized | NBK | The last cold forming process is followed by annealing above the upper transformation point in a controlled atmosphere. |
