What is elevated-temperature steel?
For these steels the standard guarantees strength values at elevated service temperatures. That makes them the base material of every pressurised high-temperature system:
- boilers;
- steam and condensate lines;
- district heating;
- heat exchangers;
- power-plant piping.
Grade selection in brief
- P235GH, P265GH: general steam and hot-water lines.
- 16Mo3: higher temperatures.
- 13CrMo4-5, 10CrMo9-10: Cr-Mo steels for power-plant and high-temperature steam.
- P91, P92: the highest-temperature main lines.
Exact limits come from the applicable standard and your designer.
Testing and documentation
- Test category: TC1 or TC2, depending on the pressure-equipment classification. TC2 includes non-destructive (e.g. ultrasonic) testing.
- Certificates: every delivery comes with EN 10204 3.1, and 3.2 on request.
- Nuclear execution: to special requirements (e.g. RCC-M) on request.
Extras
- random or cut lengths, with bevelled ends;

Frequently asked questions
What does "GH" mean in P235GH?
"G" stands for other characteristics and "H" for high temperature. The designation means steel for pressure purposes at elevated temperature.
Do you supply the complete steam-line package?
Yes. See our steam-line guide for details.
