Main Feature
1.high precision, saves the loss quantity when machining users
2.Specifications, wide range of applications
3.cold rolled finished products with high precision, good surface
quality and good linearity.
4.Steel pipe diameter can be made into hexagonal
5.steel pipe superior performance, comparatively dense metal
Advantage
Internal and external walls without oxide layer
to withstand high pressure without leakage
Cold bending deformation
Flattening without cracks
best bright finish
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
