Inconel X750 round bars are cylindrical rods made from a nickel-based superalloy engineered for high-temperature stability and corrosion resistance. The alloy's microstructure is strengthened through precipitation hardening, primarily by aluminum and titanium, which gives it superior creep resistance, fatigue strength, and dimensional stability under stress. Typical chemical composition includes at least 70% nickel, 14–17% chromium, 2.25–2.75% titanium, and 0.4–1.0% aluminium. The alloy’s density is around 8.28 g/cm³, with a melting range near 1,430 °C, and a yield strength of approximately 868 MPa, based on AMS or ASTM data.

Inconel X750, with UNS designation N07750 (also known by its Werkstoff number 2.4669), is a precipitation-hardenable nickel-chromium-titanium alloy that retains high tensile strength at elevated temperatures and resists relaxation under stress. It is often supplied in line with ASTM B637 / ASME SB637 specifications, making it suitable for critical high-temperature applications.

Inconel X750 round bars from SMM Industries LLP deliver a host of advantages: Exceptional high-temperature strength — maintains mechanical integrity up to 704 °C (1,300 °F) thanks to the precipitation-hardening mechanism. Excellent oxidation resistance — forms a stable oxide layer even at elevated temperatures, protecting against corrosion in harsh environments.

Superior creep and fatigue resistance under cyclic or sustained loads, making it ideal for springs, fasteners, and turbine components. High mechanical stability — resists distortion and relaxation under stress, which is critical for precision parts. Versatility in surface finishes and forms — available in bright, black, polished, peeled or ground finishes, and in round, hex, square, or hollow bar forms. Wide standard compliance — manufactured to ASTM B637 / ASME SB637 grade and available in AMS and other specifications.

Inconel X750 round bars are deployed in a variety of high-performance applications across industries. Key uses include:

• Aerospace components: used in turbine blades, fasteners, and flame-holding hardware where high temperature strength and corrosion resistance are essential.

• Power generation: employed in gas turbine parts, springs, and rotor components subjected to thermal stress.

• Nuclear industry: used in reactor control systems, springs, and components exposed to radiation and high heat.

• Oil & Gas: used in petrochemical furnace parts, superalloy piping, and high-pressure fittings that demand both corrosion and heat resistance.

• Chemical processing: used in reactors, valves, and heat exchanger components where exposure to aggressive environments is common.

• Automotive & Motorsports: used in exhaust systems, turbocharger components, and high-temperature springs.

• Industrial equipment: used in springs, fasteners, and precision machined components that must withstand repeated thermal cycling.

Inconel X750 round bars are recognized under different standards across regions. Some of the alternative names and equivalents: UNS: N07750, Werkstoff (Germany): 2.4669, JIS (Japan): NCF X-750, EN / European: NiCr 15Fe7TiAl alloy, AMS: AMS 5667 / AMS 5668 / AMS 5669 series. These various identifiers ensure compatibility and traceability across global supply chains.
