carbon small diameter precision cold drawn seamlesssteel pipe

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

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
