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.

Packages:

In bundles or in wooden box packages.
