Delivery condition and precision tubes surface
|
| Precision tubes are supplied in condition that is presented in the table below. It is marking for thermal processing according to EN 10305-1. |
| +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 | Annealed. After the last cold drawing process the tubes are annealed in a controlled atmosphere. |
| +N |
Normalized. After the last cold drawing process the tubes are annealed in a controlled atmosphere |
Manufacturing of precision tube
Starting from steel strip continuing with the formation and welding, annealing, surface treatment, threading, drawn, cutting tips, long commercial cuts, non-destructive testing, packaging and finally dispatching once the finished tube is obtained, according to customer requirements.
Precision tubes are finished up by bright annealing or special cold drawing. Precision tubes corresponds to the usage in which a high surface quality and excellent dimensional accuracy are demanded for the semiconductor, for automotive, for the medical treatment and for food etc..
Example of application
・For the semiconductor
・For automotive
・For the medical trearment
・For food
