Delivery condition:
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 plastically, the plastically 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
Product Process:
1.Pickling/phosphating
2.Cold Drawn
3.Stress Relieve/Annealed
4.Sawing&Straightening
5.Straightness and Dimission Inspecting
6.Lathe
7.SRB/Honed
8.Surface Polishing
9.Finished products
10.Pacakage:
Application:
1.Hydraulic Cylinder Tube---Used in the hydraulic cylinder of the heavy machinery, Cranes, excavator also forklifts. Material is various, mainly STKM-13CT, ST52, CK45 and 1020. We can work and get the mechanical property of the clients need and extended the life of the hydraulic cylinder.
2.SRB tube ----- Used in Elevator,buffer and Hydraulic Cylinder .This kind tube have a better roughness inner the tube, ra0.2-0.4um and can use directly in the hydraulic cylinder tube.
Range: ID 50-250mm and Length can work at most 6M.
3.Cold finished tube---- Widely Used. Processing range 30-300mm, biggest length is 11M.
