### **Product Introduction: Alloy X-750 / Inconel X-750 Forgings (UNS N07750)** #### **Overview** **Alloy X-750 Forgings** (commercially known as **Inconel® X-750 Forgings**) represent the premium form of this precipitation-hardenable nickel-chromium superalloy, specifically engineered for critical applications demanding exceptional high-temperature strength and reliability. The forging process significantly enhances the alloy's grain structure, mechanical properties, and metallurgical integrity throughout the component. Inconel X-750 forgings deliver outstanding strength retention, excellent creep rupture properties, and superior oxidation resistance at temperatures up to 700°C (1300°F), making them indispensable for aerospace, nuclear, and high-temperature industrial applications. The combination of specialized forging techniques and the alloy's unique precipitation-hardening capability through gamma prime [γ'-Ni₃(Al,Ti)] phase formation results in components with optimized grain flow, improved fatigue resistance, and enhanced mechanical properties for the most demanding service conditions. --- #### **Chemical Composition** The chemical composition of Alloy X-750 Forgings (UNS N07750) meets rigorous international standards: | Element | Content (%) | |---------|-------------| | **Nickel (Ni)** | 70.0 minimum | | **Chromium (Cr)** | 14.0 -
