Overview of Inconel Alloy 718

718 inconel is a nickel-chromium alloy known for its exceptional high-temperature strength, corrosion resistance, and outstanding weldability, especially in the age-hardened condition. It is precipitation-hardenable, making it one of the most widely used superalloys in aerospace, energy, and marine industries.

Key Features of Inconel Alloy 718 (All Forms)

Excellent High-Temperature Strength

• Maintains strength up to 700°C (1300°F).
• Superior creep-rupture resistance, ideal for long-term service at high temps.

Outstanding Corrosion and Oxidation Resistance

• Excellent resistance to oxidation, chloride stress corrosion, pitting, and general corrosion in harsh environments.
• Performs well in aerospace, chemical, and marine atmospheres.

Precipitation Hardening for High Strength

• Strengthened via precipitation of gamma prime (γ') and gamma double prime (γ″) phases.
• Very high yield, tensile, and fatigue strength even after long service at elevated temperatures.

Excellent Weldability

• Unlike many high-strength alloys, Inconel 718 has excellent weldability without risk of post-weld cracking.
• Used extensively in welded structural components.

Resistance to Mechanical Fatigue & Stress

• High resistance to mechanical fatigue, thermal fatigue, and vibration.
• Suitable for rotating parts like turbine discs and shafts.

718 alloy Form-Specific Applications

Bar / Rod

• Used for aircraft engine parts, fasteners, bolts, shafts, and load-bearing structures in hot zones.
• High tensile strength and fatigue resistance.

Wire

• Inconel 718 wire is ideal for spring wire, lock wire, welding filler wire, and high-temp fastening systems.
• Inconel 718 filler wire has good ductility and strength.

Forging

• Forged into turbine discs, rings, shafts, flanges, and rotor parts.
• Excellent stability under high mechanical stress.

Plate / Strip

• Used in gas turbines, rocket engines, chemical vessels, and nuclear power plant components.
• Great formability and post-weld strength retention.
