Anti-corrosion Packing
Final Supply Conditions

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
