Delivery Conditions
The tubes shall be manufactured from hot-finished seamless tubes by cold drawing or other suitable processes. The tubes shall be supplied in one of the delivery conditions as follows.
| Designation | Symbol | Description |
| Cold-drawn/hard | +C | No heat treatment after the final cold drawing process |
| Cold-drawn/soft | +LC | After the final heat treatment, there is a suitable drawing pass |
| Cold drawn and stress relieved | +SR | After the final cold drawing process, there is a stress relief heat treatment in a controlled atmosphere |
| Annealed | +A | After the final cold drawing process, the tubes are annealed in a controlled atmosphere |
| Normalized | +N | After the final cold drawing operation, the tubes are normalized in a controlled atmosphere |
