Nimonic 80A aging enhanced ni-based deformation high temperature alloy

Nimonic 80A characteristics and application fields of summary:

GH80A nickel chrome is as matrix, adding aluminum, titanium drive into the high temperature alloy strengthening phase dispersion, except the aluminum content slightly tall outside, other and GH4033 close, use 700 ~ 800 °C temperature, in 650 ~ 850 °C with good make creep properties and make oxidation performance. The alloy hot working performance is good. The alloy used to make the engine rotor blades, guide blade bearings, bolts, YePianSuo board parts.

Nimonic 80A Adavantage:

Advantage:

1.Can precipitate hardening of the alloy, high temperature (maximum 815 C) stretching of excellent

2.Ship diesel engine with tanks, the exhaust valve mainly USES the Nimonic80A forged from the system. 

Nimonic80A has the very high heat resistance, high strength at high temperature, the deformation resistance, 

increase the difficulty of forging forming. Suitable for manufacturing bolt, the exhaust valve combustion chamber.
