### **Product Datasheet: Alloy X / Inconel® HX Fittings (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. This solid-solution strengthened alloy demonstrates exceptional resistance to oxidation, carburization, and various corrosive environments while maintaining high strength at temperatures up to 1200°C (2200°F). **Inconel HX Fittings** are precision-engineered components designed for connecting piping and tubing systems in the most demanding high-temperature applications. These fittings maintain system integrity under thermal cycling, pressure stresses, and aggressive chemical environments, making them essential for critical processing systems across various industries. --- ### **1.
