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
