Nicrofer® 3220 H - alloy 800 H
The analysis is similar to that of Nicrofer 3220, but a special solution anneal treatment (with grain sizes = 90 µm/ASTM No. 4) gives significantly increased creep-rupture strength above 600 °C (1110 °F).
For services below 600 °C (1110 °F) the use of soft annealed Nicrofer 3220 is suggested.
Nicrofer 3220 H is characterized by:
- good creep-rupture properties at temperatures above 600 °C (1110 °F) without loss of ductility during long-term use at temperatures below 700 °C (1290 °F), due to limitation of (Ti + Al) content to max. 0.7 %
- good resistance to reducing, oxidizing and nitriding
- metallurgical stability in long-term application at high temperatures
