Processing : cold drawn cold rolled honed SRB Burnish
Delivery condition of hydraulic cylinder tube:
1.NBK(+N) of hydraulic tube
after cold forming, eventually above phase transition point, in a protective atmosphere of annealing oxidation medium
2. GBK(+A) of hydraulic cylinder tube
after cold forming, annealing in non oxidizing medium protective gas
3. BK(+C) of honed tube
the final heat treatment after cold forming, therefore small steel pipe plastically, the plastically degree does not guarantee
4. BKW(+LC) of hydraulic cylinder 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 honed 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
