### **Product Introduction: Alloy X-750 / Inconel X-750 Sheet (UNS N07750)** #### **Overview** **Alloy X-750 Sheet** (commercially known as **Inconel® X-750 Sheet**) is a precipitation-hardenable nickel-chromium alloy supplied in thin, flat-rolled form, offering an excellent combination of high strength, good corrosion resistance, and outstanding oxidation resistance up to 700°C (1300°F). This age-hardenable superalloy sheet maintains superior mechanical properties under high-temperature conditions and provides excellent creep rupture strength, making it particularly suitable for formed, stamped, and fabricated components in aerospace, nuclear, and industrial applications requiring reliable performance in demanding thermal environments. The sheet product undergoes precision rolling and controlled heat treatment processes to ensure consistent gauge control, superior surface quality, and reliable performance in critical applications. --- #### **Chemical Composition** The chemical composition of Alloy X-750 Sheet (UNS N07750) is carefully balanced for optimal performance: | Element | Content (%) | |---------|-------------| | **Nickel (Ni)** | 70.0 minimum | | **Chromium (Cr)** | 14.0 -

Alloy X-750 sheet is typically supplied in the solution annealed condition for optimum formability, with subsequent aging treatment to develop high mechanical properties. The material demonstrates good weldability but requires proper post-weld heat treatment to restore properties in the heat-affected zone. Proper handling and storage in controlled environments are essential to prevent surface damage and contamination. Comprehensive material certification is provided for all critical applications.* *Correction: The correct UNS designation for Inconel X-750 is N07750, not N07752 as mentioned in the request. All technical information provided corresponds to UNS N07750.*
