### **Product Introduction: Alloy X-750 / Inconel X-750 Tube (UNS N07750)** #### **Overview** **Alloy X-750 Tube** (commercially known as **Inconel® X-750 Tube**) is a high-performance nickel-chromium alloy tubing product specifically engineered for applications requiring excellent strength and oxidation resistance at temperatures up to 700°C (1300°F). This precipitation-hardenable alloy maintains outstanding mechanical properties under high-temperature conditions and offers good creep rupture strength, making it ideal for aerospace, nuclear, and industrial applications where reliability in demanding thermal environments is crucial. The tube is manufactured through precision processes to ensure consistent wall thickness, superior surface finish, and reliable performance in critical high-temperature applications. --- #### **Chemical Composition** The chemical composition of Alloy X-750 Tube (UNS N07750) is carefully balanced for optimal performance: | Element | Content (%) | |---------|-------------| | **Nickel (Ni)** | 70.0 minimum | | **Chromium (Cr)** | 14.0 -
