Inconel 718 is a high-performance nickel-chromium alloy primarily used in extreme high-temperature applications. It is a precipitation-hardenable alloy that combines excellent strength and corrosion resistance at elevated temperatures, making it highly suitable for use in the aerospace, power generation, and other industries where materials are subjected to high thermal and mechanical stresses.
Key Characteristics of Inconel 718:
- High Strength: Inconel 718 maintains its strength even at temperatures up to 700°C (1,300°F), and can withstand even higher temperatures for short periods.
- Excellent Corrosion and Oxidation Resistance: The alloy has excellent resistance to oxidation, carburization, and other forms of high-temperature corrosion, especially in harsh environments such as those found in jet engines and gas turbines.
- Good Weldability: Inconel 718 has relatively good weldability compared to other high-temperature alloys, making it easier to fabricate and repair.
- Precipitation-Hardening: The alloy is age-hardened to develop high tensile and yield strengths, as well as resistance to creep and stress rupture, by the precipitation of strengthening phases like γ′ (gamma prime) and γ″ (gamma double prime) during heat treatment.
- Resistance to Thermal Fatigue: It exhibits good resistance to thermal fatigue and thermal shock, which makes it ideal for components exposed to cyclical heating and cooling.
- Creep Resistance: The alloy performs well under long-term stress at elevated temperatures, which is crucial for components that experience prolonged exposure to high stress, such as turbine blades.
Chemical Composition (Approximate):

Heat Treatment Process for Inconel 718:
Inconel 718 can be heat-treated to achieve optimal mechanical properties. The typical heat treatment process involves:
- Solution Annealing: Heated to a high temperature (around 1,200°C or 2,190°F) to dissolve the precipitates, followed by rapid cooling.
- Aging: The alloy is then aged at a lower temperature (around 720°C or 1,330°F) for a period of time to allow the strengthening precipitates (γ′ and γ″) to form.
Advantages of Inconel 718:
- Superior High-Temperature Performance: It can operate in environments with temperatures up to 700°C (1,300°F) for extended periods, maintaining its strength and resistance to corrosion.
- Excellent Weldability: Unlike many high-temperature alloys, Inconel 718 can be welded and fabricated using common techniques.
- Long-term Durability: The alloy's resistance to oxidation and corrosion makes it ideal for long-term applications in extreme conditions.
- Fatigue Resistance: Inconel 718 maintains its strength under cyclic loading, which is essential for components in jet engines and turbines.
