 Delivery ConditionTermSymbolExplanationCold-finished/hard
(cold-finished as-drawn)
BKNo heat treatment after the last cold-forming process. The tubes therefore have only low deformability.Cold-finished/soft
(lightly cold-worked)
BKWAfter 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.AnnealedGBKAfter the final cold-forming process the tubes are annealed in a controlled atmosphere or under vacuum.NormalizedNBKThe tubes are annealed above the upper transformation point in a controlled atmosphere or under vacuum.
