Delivery conditions

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 plastic, the plastic 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 again
