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-relleved BKS Heat treatment is applled 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
