    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)
