BK means that the tubes do not undergo heat treatment
BKW means the final heat treatment is followed by cold drawing involving limited deformation
Appropriate further processing allows a certain degree of cold forming
BKS means Heat treatment is applied following the last cold forming process
GBK means the last cold forming process is followed by annealing
NBK means the last cold forming process is followed by annealing above the upper transformation point in a controlled atmosphere.
