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