### **Product Datasheet: Alloy X / Inconel® HX Pipe (UNS N06002)** **Alloy X** (commercially known as **Inconel® HX** and standardized as **UNS N06002**) is a nickel-chromium-iron-molybdenum superalloy renowned for its exceptional high-temperature strength and outstanding resistance to oxidation, carburization, and a variety of corrosive atmospheres. The **pipe** product form of Inconel HX is engineered for conveying aggressive gases and fluids, as well as for structural applications in extreme thermal environments, typically up to 1200°C (2200°F). Its excellent fabricability and weldability make it a prime choice for constructing high-temperature piping systems in critical industries. --- ### **1. Chemical Composition** The typical chemical composition of Inconel HX (UNS N06002) pipe is as follows (balance is Nickel): | Element | Content (%) | | :--- | :--- | | **Nickel (Ni)** | Balance | | **Chromium (Cr)** | 20.5 - 23.0 | | **Iron (Fe)** | 17.0 - 20.0 | | **Molybdenum (Mo)** | 8.0 - 10.0 | | **Cobalt (Co)** | 0.5 - 2.5 | | **Tungsten (W)** | 0.2 - 1.0 | | **Carbon (C)** | 0.05 - 0.15 | | **Manganese (Mn)** | ≤ 1.00 | | **Silicon (Si)** | ≤ 1.00 | | **Phosphorus (P)** | ≤ 0.040 | | **Sulfur (S)** | ≤ 0.030 | | **Boron (B)** | ≤ 0.010 | * **Key Role of Elements:** * **Ni (Nickel):** Provides the austenitic matrix, offering inherent corrosion resistance and microstructural stability at high temperatures. * **Cr (Chromium):** Confers excellent resistance to oxidation and sulfidation, crucial for furnace atmospheres. * **Mo & W (Molybdenum & Tungsten):** Act as solid-solution strengtheners, providing high-temperature creep strength. * **C (Carbon):** Enhances elevated temperature strength. --- ### **2.
