Overview


NIMONIC alloy 90 (UNS N07090/W. Nr. 2.4632) is a wrought nickel-chromium-cobalt base alloy strengthened by additions of titanium and aluminum. It has been developed as an age-hardenable creep- resisting alloy for service at temperatures up to 920°C (1688°F.) It is widely used and a well proven alloy in high temperature conditions. Some typical applications for Nimonic® 90 include turbine blades, discs, forgings, ring sections, hot-working tools and other extreme environments.

 Corrosion Resistance


Nimonic alloy 90 has excellent creep resistance, high creep rupture strength and good ductility. With high chromium content, Alloy 90 offers a good resistance to high temperature corrosion and oxidation resistance.


Heat Treatment


The heat treatments recommended are as follows: Bar 8 h/1080°C(1975°F)/AC + 16 h/700°C (1290°F)/AC Sheet 3 min/1150°C(2100°F)/FBQ or WQ + 1 h/925°C(1700°F)/AC + 4 h/750°C (1380°F)/AC Welded sheet 3 min/1150°C(2100°F)/FBQ or WQ + weld + 1 h/925°C(1700°F)/AC + 4 h/750°C(1380°F)/AC Interstage anneal of sheet 20 min/1040°C (1900°F)/AC or WQ
