Nicrofer® 3220 HP - alloy 800 HP
A special solution anneal treatment (with grain sizes = 90 µm/ASTM No. 4) gives highest creep-rupture strength above 700 °C (1290 °F) due to the precipitation of TiC.
Below 700 °C (1290 °F), gamma prime (?´) precipitates combined with loss of ductility.
Nicrofer 3220 HP is characterized by:
- excellent creep strength at temperature above 700 °C (1290 °F) However, for applications where frequent excursions to temperatures lower than 700 °C (1290 °F) during service cannot be excluded or parts of the material are permanently exposed to a temperature below 700 °C (1290 °F), the use of Nicrofer 3220 H is recommended.
- good resistance to reducing, oxidizing and nitriding atmospheres and to atmospheres which alternate between reducing and oxidizing conditions
- metallurgical stability in long-term application at high temperatures
