Delivery Condition:

Delivery Condition Specification
BK ( +C )

Tubes don't undergo heat treatment following the final cold forming,thus have a rather hig-h resistance to deformation

BKW ( +LC )

The final heat treatment is follwed by cold drawing involving limted deformation. Appopriat-e further processing allows a certain degree of cold droming( eg: handing expanding)

BKS ( +SR )

Heat treatment is applied following the last cold forming process, subject to appropriate

 procession conditions, the increate in the residual stresses,involved enables both forming 

and maching to a certain degress.

GBK ( +A )The last cold forming process followed by annealing in controlled atmosphere.
NBK (+N )
