### **Product Introduction: Alloy X-750 / Inconel X-750 Plate (UNS N07750)** #### **Overview** **Alloy X-750 Plate** (commercially known as **Inconel® X-750 Plate**) is a precipitation-hardenable nickel-chromium alloy supplied in plate 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 plate maintains superior mechanical properties under high-temperature conditions and provides excellent creep rupture strength, making it suitable for aerospace, nuclear, and industrial applications requiring reliable performance in demanding environments. The plate product undergoes controlled thermo-mechanical processing and precise heat treatments to ensure uniform grain structure, consistent properties throughout the thickness, and reliable performance in critical applications. --- #### **Chemical Composition** The chemical composition of Alloy X-750 Plate (UNS N07750) is carefully balanced for optimal performance: | Element | Content (%) | |---------|-------------| | **Nickel (Ni)** | 70.0 minimum | | **Chromium (Cr)** | 14.0 -
