Commodity:

Michanical Performance of carbon tube:

Delivery condition:

1.  NBK(+N) of hydraulic cylinder pipe

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

2. GBK(+A) of carbon tube

after cold forming, annealing in non oxidizing medium protective gas

3. BK(+C) of precision tube

the final heat treatment after cold forming, therefore small steel pipe plastically, the plastically degree does not guarantee

4. BKW(+LC) of carbon tube

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) of hydraulic 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
