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-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.
