Familia genérica: Nickel - Wrought - Ni-Fe-Cr Alloy • Suministrado por: Outokumpu

Characteristics of Nicrofer 3220 HP - alloy 800 HP Nicrofer 3220 HP is an austenitic high-strength solid-solution nickel-iron-chromium alloy with controlled levels of carbon, aluminium, titanium, silicon and manganese and increased content of (Al + Ti).

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
