High Tensile Strength: Inconel 718 exhibits high tensile, creep, and rupture strength, particularly at elevated temperatures, making it ideal for applications subject to extreme stresses.

Yield Strength: The alloy has a high yield strength, particularly after precipitation hardening, which contributes to its excellent structural integrity.

Fatigue Resistance: The alloy's ability to resist fatigue is excellent, making it suitable for parts that undergo repeated cycles of stress and strain.

Ductility: Inconel 718 has good ductility, allowing it to be used in various complex applications and forming processes.

Corrosion and Oxidation Resistance:

Oxidation Resistance: Inconel 718 performs well in high-temperature oxidative environments, preventing oxidation at elevated temperatures.

Corrosion Resistance: It is highly resistant to corrosion, particularly in acidic and alkaline environments, which makes it suitable for harsh chemical processing conditions.

Sulfur and Chlorine Resistance: It offers good resistance to sulfur and chlorine compounds, which are common in the power and petrochemical industries.

• Welding and Fabrication:

Weldability: Inconel 718 is known for its good weldability, though care must be taken to prevent cracking, especially when welding at high temperatures.

Formability: The alloy can be formed into various shapes (such as wire, sheet, bar, or tube), and it is often used in the form of wire in applications that require precise structural integrity and strength at high temperatures.

• Wire Form:

Inconel 718 Wire: The wire form is commonly used in welding, electrode applications, and as reinforcement material in high-stress components.

Electrical Applications: Inconel 718 wire is often used in thermocouple applications and electrical components that require high-temperature stability and resistance to oxidation.

• Fabrication and Processing:

Inconel 718 can be processed using conventional techniques like forging, machining, and casting. However, due to its high strength and hardness at elevated temperatures, specialized processes such as electrical discharge machining (EDM) are sometimes used for complex geometries.

Applications:

• Aerospace: The alloy is commonly used in the aerospace industry for turbine blades, seals, and other high-stress, high-temperature components.
• Power Generation: Inconel 718 is used in gas turbines, steam turbines, and exhaust systems where high strength and corrosion resistance are critical.
• Chemical Processing: Due to its corrosion resistance, the alloy is used in reactors, heat exchangers, and other chemical process equipment.
• Automotive: Inconel 718 is also used for parts that operate in extreme environments, such as in turbochargers and exhaust systems.
• Nuclear: This alloy is used in nuclear reactors and power plants due to its resistance to high radiation and temperature conditions.

Summary:

Inconel 718 (GH4169/UNS N07718/2.4668) is a high-performance nickel-chromium alloy wire designed for extreme temperature and high-stress applications. Its high strength, excellent oxidation and corrosion resistance, and good weldability make it ideal for use in aerospace, chemical processing, power generation, and other industries requiring reliable performance under severe conditions.

Its primary characteristics include:

• High temperature resistance up to 1000°C (1832°F)
