Heat Treatment/      Delivery ConditionCold finished (hard)   BK(+C)
Tubes do not undergo heat treatment following the final cold forming and, thus, have a rather high resistance to deformation
Cold finished (soft)    BKW(+LC)
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-relieved annealing BKS(+SR)
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(+A)
The last Cold forming process is followed by annealing in a controlled atmosphere.
Normalized   NBK(+N)
The last cold forming process is followed by annealing above the upper transformation point in a controlled atmosphere.
Delivery TimeWithin 35-50 days from receiving deposit
Payment Term100% L/C at sight or 30% deposit, 70% balance against copy of B/L
Usage/ApplicationPipes for automobile and motorcycle
