GH4169 is a widely used nickel-based superalloy (domestic equivalent grade of Inconel® 718 alloy), renowned for its excellent high-temperature strength, good corrosion resistance, and processability. It plays a crucial role in aerospace, energy, chemical engineering, and other fields. The following is a detailed introduction from aspects such as composition, performance, and applications:

I. Chemical Composition

GH4169 is based on nickel (approximately 50%-55%), with main alloying elements including:

 

Chromium (Cr): 17%-21% (improves corrosion resistance and oxidation resistance)

Iron (Fe): Balance (approximately 10%-15%)

Niobium (Nb) + Tantalum (Ta): 4.75%-5.5% (strengthens through the precipitation of γ'' phase, serving as key strengthening elements)

Molybdenum (Mo): 2.8%-3.3% (solidsolution strengthening, enhances high-temperature strength)

Titanium (Ti): 0.65%-1.15% (assists in strengthening and promotes the precipitation of γ' phase)

Aluminum (Al): 0.2%-0.8% (works synergistically with titanium to enhance the strengthening effect of γ' phase)

Trace impurity elements (C, Mn, Si, S, etc., whose contents must be strictly controlled to avoid performance degradation).

 

The core of its composition design lies in achieving strengthening through the precipitation of γ' phase (Ni₃(Al,Ti)) and γ'' phase (Ni₃Nb), while utilizing elements such as chromium and molybdenum to improve corrosion resistance and high-temperature stability.
