Symbol

Explanation

Cold-finished/hard
(cold-finished as-drawn)

BK

No heat treatment after the last cold-forming process. The tubes, therefore, have only low deformability.

Cold-finished/soft
(lightly cold-worked)

BKW

After the last heat treatment, there is a light finishing pass (cold drawing) With proper subsequent processing, the tube can be cold-formed (e.g. bent, expanded) within certain limits.

Annealed

GBK

After the final cold-forming process the tubes are annealed in a controlled atmosphere or under vacuum.

Normalized

NBK

The tubes are annealed above the upper transformation point in a controlled atmosphere or under a vacuum.
