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

1. 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)

1. 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.

1. Annealed    GBK(+A)

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

1. Normalized   NBK(+N)

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