Nimonic 105 |
UNS N06075 |
GENERAL PROPERTIES
Nimonic alloy 90 is a wrought nickel-chromium-cobalt base alloy strengthened by additions of titanium and aluminium. It has been developed as an age-hardenable creep resisting alloy for service at temperatures up to 920°C (1688°F). The alloy is used for turbine blades, discs, forgings, ring sections and hot-working tools.
RESISTANCE TO CORROSION
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.

WELDING
Welding techniques recommended for Nimonic 105 include gas-tungsten arc welding, gas metal-arc welding, submerged-arc welding and shielded metal-arc welding. Usage of a matching alloy filler metal is recommended for the welding process and if a matching filler is absent, an alloy rich in Ni, Co, Cr, Mo is can be used. During the absence of a matching filler metal.
HEAT TREATMENT
Nimonic 105 can be heat treated in 4 four steps. The steps are as follows:
Solution annealing for 4 h at 1149°C (2100°F) followed by air cooling.
Heating for 16 h at 1056°C (1925°F) followed by air cooling.
Heating for 16 h at 849°C (1560°F).
Air cooling to reach precipitation-hardening.
