Delivery Condition

1. BK(+C)
the final heat treatment after cold forming, threfore small steel pipe plasticly, the plasticly degree does not guarantee
2. 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 again 
3. NBK(+N)
after cold forming, eventually above phase transition point, in a protective atmosphere of annealing oxidation medium
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. GBK(+A)
after cold forming, annealing in non oxidizing medium protective gas
