Delivery Condition of seamless pipe

1. BK(+C) of hydraulic tube

the final heat treatment after cold forming, threfore small steel pipe plasticly, the plasticly degree does not guarantee

2. BKS(+SR) of cylinder tube

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) of hydraulic cylinder tube

after cold forming, eventually above phase transition point, in a protective atmosphere of annealing oxidation medium

4. BKW(+LC) of hydraulic cylinder pipe

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) of hydraulic steel pipe

after cold forming, annealing in non oxidizing medium protective gas
