Product Description
Nimonic 90 is a precipitation-hardenable nickel-chromium-cobalt alloy having high stress-rupture strength and creep resistance at temperatures to about 1700°F (920°C). Nimonic 90 also has good resistance to high-temperature corrosion and oxidation. Nimonic 90 is used for blades and discs in gas turbines, hot-working tools, and springs.
Available forms of Nimonic 90 are round, flats, extruded section, plate, sheet, strip, tube, and wire.
Nimonic 80A alloy is a nickel-chromium alloy that is strengthened by the additions of titanium and aluminum. It has high tensile and creep-rupture properties at temperatures up to 815°C (1500°F).
NIMONIC alloy 80A is currently used for gas turbine components (blades, rings and discs), bolts, nuclear boiler tube supports, die casting inserts and cores, and for automobile exhaust valves
Nimonic alloy 90 is a precipitation hardenable nickel-chromium-cobalt alloy strengthened by the addition of Titanium and Aluminium. Alloy 90 has a high stress rupture strength and creep-resistant at temperatures to 920°C. Nimonic Alloy 90 is typically used in extreme stress applications such as turbine blades, hot working tools, exhaust reheaters, disc and high-temperature springs.
The recommended heat treatments for Nimonic 90 are as follows:
Nimonic 90 Bar
Solution Treatment - 1080 °C (1975 °F) for 8 hours + air cool or oil/ water quench
Precipitation Heat Treatment (As per BS HR2) - 700 °C (1290 °F) for 16 hours + air cool
Nimonic 90 Sheet
Solution Treatment - 1100-1150 °C for 1-10 minutes + air cool or oil /water quench
Stabilization Heat Treatment - 925 °C for 1 hour + air cool
Precipitation Heat Treatment - 750 °C for 4 hours and air cool
(BS HR202/ MSRR 7016 / Siemens TLV 85252100 do not require the Stabilization Treatment stage)
