Heat Treatment/ Delivery Condition

1.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

2.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)

3.Cold finished and stress-relieved annealing 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.

4.Annealed GBK(+A)

The last Cold forming process is followed by annealing in a controlled atmosphere.

5.Normalized NBK(+N)

The last cold forming process is followed by annealing above the upper transformation point in a controlled atmosphere.
