Final Supply Conditions
| Designation |

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-relleved |
BKS |
Heat treatment is applled 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 |
