DIN St 30 Si Heat Treatments
- 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.
