Inconel X-750 Wire /N 07750/2.4669 Bar / Rod / Wire / Forging / Plate / Strip For High Mechanical Stresses And Extreme Temperatures

Inconel X-750 (UNS N07750 / W.Nr. 2.4669) is a nickel-chromium alloy made precipitation-hardenable by additions of titanium and aluminum. It offers excellent high-temperature strength, creep resistance, and oxidation resistance up to 980°C (1800°F). Widely used in aerospace, gas turbines, and nuclear reactors, it maintains mechanical properties under thermal stress and cyclic conditions. Its forms — Bar, Rod, Wire, Forging, Plate, and Strip — are suited for springs, bolts, turbine blades, and structural components. Inconel X-750 also resists corrosion and stress corrosion cracking, particularly in high-temp oxidizing and chloride-rich environments. It is easily fabricated and welded, making it a reliable choice for demanding high-performance applications.

Overview of Inconel X-750

Inconel X-750 is a precipitation-hardenable nickel-chromium alloy made for high strength and oxidation resistance at temperatures up to ~700°C (1300°F). It’s especially well-known for its excellent performance in high-temperature, high-stress environments, both in static and rotating components.

Key Features (All Forms)

High Temperature Strength

• Maintains high tensile and creep-rupture strength at elevated temperatures.
• Effective in applications up to 704°C (1300°F), and even higher with reduced stress.

Oxidation and Corrosion Resistance

• Resists oxidation, carburization, and chloride-induced corrosion.
• Works well in aerospace, nuclear, and chemical processing environments.

Good Stress Corrosion Cracking Resistance

• Particularly resistant to stress corrosion cracking (SCC) in high-temperature, high-stress conditions.
• Excellent behavior in chloride-containing and aqueous media.

Good Fabricability & Weldability

• Can be formed using standard cold and hot working techniques.
• Can be welded using standard procedures (typically GTAW), but post-weld heat treatment may be necessary to regain full properties.

Age-Hardenable

• Strength is achieved via precipitation hardening, typically using a solution anneal followed by aging treatment.
