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.

• 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
