Delivery condition of CDW Precision Steel Tube :

 
NBK (+N) Normalized. (Mainly focus on) After the final cold forming process the tubes are annealed above the upper
transformation point in a controlled atmosphere
Other conditions as per standard En10305.
BK (+C) Cold finished/hard (cold finished as drawn) No heat treatment after the last cold forming process.
BKW (+LC) Cold finished/soft (lightly cold worked)
After the last heat treatment there is a light finishing pass (cold drawing).
BKS (+SR) Cold finished/stress relieve annealed. After the final cold forming process the tubes are stress relieve
annealed.
GBK (+A) Annealed After the final cold forming process the tubes are annealed in a controlled atmosphere

What we do on production.

1.We adopt special techniques and special skills in the acid cleaning process to deal with the place where

it is easy to form fold crevice;

2.Well organized process,especially annealing treatment in a severely technical manner;

3.In respect with lubrication, we adopt the international advanced level treating process in the world, and put

the surface quality of our products under strict control in order to prevent causing surface crack.
