### **Product Datasheet: Alloy X / Inconel® HX Forgings (UNS N06002)** **Alloy X** (commercially known as **Inconel® HX** and standardized as **UNS N06002**) is a nickel-chromium-iron-molybdenum superalloy specifically engineered for extreme high-temperature service. The **forged** product form of this solid-solution strengthened alloy offers superior mechanical properties and structural integrity compared to cast or wrought forms, making it ideal for the most demanding high-stress applications. Forged Inconel HX components demonstrate exceptional resistance to oxidation, carburization, and various corrosive environments while maintaining outstanding strength and creep resistance at temperatures up to 1200°C (2200°F). The forging process enhances grain structure, eliminates porosity, and improves directional strength, resulting in components with unparalleled reliability in critical service conditions. --- ### **1.
