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 |
