Cold Drawing Carbon Steel Tube E215 , Precision Steel Tube EN 10305-1/4
1.Precision steel tube-carbon steel are made using the cold drawing process. Precision tubes are made from carbon steel from quality Bao Steel,XingCheng Steel,and HuaiSteel.
2. The tubes are high precision in tolerance,excellent surface brightness,no oxidization on the outer and inner walls after heat treatment,high cleanness of inside wall.
3. No deformation after cold bending,no crack after flaring and flattening.

Delivery condition and heat treatment processing of precision steel tube-carbon steel
|
Delivery Condition |
Heat treatment process |
|
+C |
Cold drawn/hard.After the last cold forming,no heat treatment. |
|
+LC |
Cold drawn/soft.After the last heat treatment follows the cold drawing there is a light finishing pass.
|
|
+SR |
Cold drawn and stress relieved annealed. After the final cold drawing process the tubes are stress relieved annealed in a controlled atmosphere. |
|
+A |
After the final cold drawing process the tubes are stress relieved annealed in a controlled atmosphere. |
|
+N |
Normalized. After the last cold drawing process the tubes are annealed in a controlled atmosphere. |
Synopsis of Process Routing: Quality Carbon steel — Cold Drawn — Heat Treatment Without Oxidization (NBK Status) — Nondestructive Testing— Flushing The Internal Hole With Special Equipment Under The High Pressure —Dealing With Antirust Oil On Surface — Plastic Capping On Both Ends.
