Good weldability, only simple stress relief required after welding without complex heat treatment
Custom hot forging, hot rolling and full CNC machining strictly per customer CAD drawings
Manufactured in compliance with ASTM B446, AMS 5542 international superalloy standards
Long service life for aerospace spring, turbine, nuclear and high-load precision components
Product Overview
This series of Inconel X750 round bars are hot forged & hot rolled solid precipitation hardening nickel alloy rods. The base material is delivered in solution annealed condition, customers can conduct aging treatment to achieve ultra-high strength and hardness. With balanced nickel, chromium, aluminum and titanium elements, X750 combines excellent high-temperature oxidation resistance, chloride corrosion resistance and supreme fatigue performance, which cannot be matched by ordinary solid-solution nickel alloys. It is the core raw material for high-temperature springs, gas turbine components, nuclear fasteners and aerospace load-bearing parts.
Material Grade Characteristics – Inconel X750 (UNS N07750 / 2.4669)
Gamma prime precipitation hardening Ni-Cr-Al-Ti alloy, gains high strength via low-temperature aging
Outstanding fatigue and creep resistance under repeated vibration and high-temperature load
Great oxidation resistance up to 815°C, stable in high-temperature air and flue gas environment
Resist chloride SCC, pitting and crevice corrosion for marine & nuclear service conditions
Retain good toughness at cryogenic temperature, no brittle fracture risk
Suitable for components requiring both high strength and long-term anti-fatigue performance

Mechanical Properties (Solution Annealed Condition A, ASTM B446)
Property
Inconel X750 Solution Annealed
Delivery Condition
Solution Annealed, Stress‑Relieved, Pickled
Minimum Tensile Strength
≥825 MPa (120 ksi)
Minimum 0.2% Yield Strength
≥415 MPa (60 ksi)
Minimum Elongation (50mm gauge)
≥30 %
Maximum Brinell Hardness
≤320 HB
Note: Much higher strength & hardness can be obtained after standard aging heat treatment.
Gamma prime precipitates greatly improve anti-vibration and anti-fatigue capacity, ideal for high-temperature springs and rotating turbine parts.
2. Wide Temperature Stability
Keep stable mechanical performance from cryogenic environment up to 815°C continuous high temperature service.
3. Combined Corrosion & Oxidation Resistance
Resist high-temperature oxidation and chloride stress cracking, superior to Inconel 600 in marine and nuclear working media.
4. Controllable Strength By Aging
Delivered soft solution state for easy CNC machining, aging process can be customized to match target hardness requirement.
5. Reliable Welding Performance
No severe sensitization after welding, only simple stress relief treatment needed without complex heat treatment.
Typical Applications
Aerospace high-temperature springs, turbine blade fasteners, engine sealing components
Nuclear power reactor internal fasteners, heat exchanger spring parts
Oil & gas high-temperature downhole springs, sour service load fittings
Industrial furnace heat-resistant springs, fixture bolts and elastic components
High-pressure gas turbine discs, elastic sealing ring blanks
Marine high-temperature corrosion resistant elastic mechanical parts
Medical precision high-strength spring and implant auxiliary components
