Delivery condition and heat treatment processing
|
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. |
Manufacturing:
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.
