Heat Treatment/      Delivery Condition

  1. Cold finished and stress-relieved annealing BKS(+SR)

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.

  1. Annealed    GBK(+A)

The last Cold forming process is followed by annealing in a controlled atmosphere.

  1. Normalized   NBK(+N)

The last cold forming process is followed by annealing above the upper transformation point in a controlled atmosphere.
