• High-Temperature Strength: Inconel 718 maintains its mechanical strength at temperatures up to 1300°F (704°C), making it suitable for high-pressure turbine blades, rocket engines, and other extreme environments.
• Corrosion Resistance: This alloy is highly resistant to oxidation, pitting, and crevice corrosion, especially in environments containing acids, salts, and other aggressive chemicals.
• Creep Resistance: Inconel 718 resists creep deformation under prolonged exposure to high stress and temperature, extending the lifespan of components in critical applications.
• Fatigue Resistance: The alloy’s excellent fatigue resistance ensures durability and reliability under cyclical loads, essential for aerospace and power generation components.

Inconel 718 parts can be easily post-hardened through precipitation-hardening heat treatments. In both as-built and age-hardened states, these parts can be machined, spark eroded, welded, micro shot-peened, polished, and coated as required. Despite its remarkable properties, the material’s anisotropy, due to the layerwise building method, must be considered in the design process.

Inconel 718’s ability to withstand extreme temperatures, high mechanical loads, and corrosive environments, combined with its excellent weldability and post-processing options, makes it a top choice for industries where failure is not an option.
