Final supply conditions

Designation Symbol 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.
