Delivery condition:
1. NBK(+N)
after cold forming, eventually above phase transition point, in a protective atmosphere of annealing oxidation medium
2. GBK(+A)
after cold forming, annealing in non oxidizing medium protective gas
3. BK(+C)
the final heat treatment after cold forming, therefore small steel pipe plastically, the plastically degree does not guarantee
4. BKW(+LC)
after final heat treatment, a tiny cold drawing deformation, continue again when machining steel pipe allowed inside certain limits cold deformation(bending, flaring)
5. BKS(+SR)
have a stress relief after cold forming, heat treatment, steel pipe can be carried out within a certain limit in the appropriate processing
