Inconel 718
Composition Analysis
Inconel 718 is a nickel-based precipitation-strengthened alloy, with carefully balanced chemical elements that contribute to its excellent properties.

Nickel (Ni) content is about 53%, serving as the primary component to provide good corrosion resistance and high-temperature stability.
Chromium (Cr) content is about 19%, enhancing oxidation and corrosion resistance.
Iron (Fe) content is about 18%, maintaining structural stability while affecting the alloy's mechanical properties.
Niobium (Nb) content is about 5%, which forms the γ'' phase (Ni₃Nb) and γ' phase (Ni₃(Al,Ti)), playing a crucial role in precipitation strengthening.
Molybdenum (Mo) content is about 3%, improving strength and corrosion resistance in complex environments.
Titanium (Ti) content is about 0.9%, and Aluminum (Al) content is about 0.5%. These elements help form the strengthening phase and improve overall mechanical performance.
