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. |
