### **Product Datasheet: Alloy X / Inconel® HX Bar (UNS N06002)** **Alloy X** (commonly known as **Inconel® HX** and standardized as **UNS N06002**) is a nickel-chromium-iron-molybdenum superalloy specifically designed for extreme high-temperature service. It exhibits exceptional strength and resistance to oxidation, carburization, and other corrosive environments up to 1200°C (2200°F). This solid-solution strengthened alloy is available in bar forms, including **round bars** and **flat bars**, which are widely used for machining and fabricating critical components in aerospace, industrial furnace, and chemical processing industries. Its excellent manufacturability, including good machinability and weldability, makes it a preferred choice for high-temperature structural applications. --- ### **1. Chemical Composition** The typical chemical composition of Inconel HX (UNS N06002) bar 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 for superior corrosion resistance and high-temperature stability. * **Cr (Chromium):** Imparts outstanding oxidation resistance. * **Mo & W (Molybdenum & Tungsten):** Act as potent solid-solution strengtheners, significantly enhancing high-temperature strength. * **C (Carbon):** Contributes to elevated temperature strength via solid solution strengthening. --- ### **2. Physical Properties** Typical physical properties for Inconel HX bar at room temperature. | Property | Metric Value | Imperial Value | | :--- | :--- | :--- | | **Density** | 8.22 g/cm³ | 0.297 lb/in³ | | **Melting Point** | 1260 - 1355 °C | 2300 - 2475 °F | | **Specific Heat (20°C)** | 455 J/kg·K | 0.109 Btu/lb·°F | | **Thermal Conductivity (20°C)** | 11.9 W/m·K | 82.7 Btu·in/hr·ft²·°F | | **Mean Coefficient of Thermal Expansion (20-1000°C)** | 14.0 μm/m·°C | 7.8 x10⁻⁶ in/in·°F | | **Electrical Resistivity** | 1.18 μΩ·m | 717 ohm·cir mil/ft | | **Modulus of Elasticity** | 205 GPa | 29.7 x 10⁶ psi | --- ### **3. Mechanical Properties (Typical for Annealed Bar)** Mechanical properties can vary with bar size and processing history. The following are typical minimum values for annealed condition as per standard specifications like ASTM B572. | Property | At Room Temperature (Typical) | | :--- | :--- | | **Tensile Strength** | ≥ 655 MPa (95 ksi) | | **Yield Strength (0.2% Offset)** | ≥ 310 MPa (45 ksi) | | **Elongation (in 50mm)** | ≥ 40% | | **Reduction of Area** | ≥ 50% | * **High-Temperature Performance:** Alloy X bar retains a significant percentage of its room-temperature strength well above 1000°C, making it suitable for load-bearing applications at extreme temperatures. --- ### **4. International Standards (Bar Products)** Inconel HX bar (Round Bar, Flat Bar) conforms to the following international standards: | Standard Body | Standard Designation | Product Form Covered | | :--- | :--- | :--- | | **ASTM International** | **ASTM B572** | Rod/Bar (This is the primary specification for UNS N06002 bar) | | **ASME** | **ASME SB-572** | Bar for use in ASME pressure vessel code construction | | **Aerospace Material Specification** | **AMS 5759** | Bars, Forgings, and Rings | | **European Standard** | **EN 10095 / EN 2.4665** | Heat resisting steels and nickel alloys (Flat & Round Bar) | | **UNS** | **N06002** | Unified Numbering System | --- ### **5. Product Applications** **Round Bar and Flat Bar** forms of Inconel HX are primarily used for machining, forging, and fabricating components that require high strength at elevated temperatures. * **Round Bar Applications:** * **Fasteners:** High-temperature bolts, studs, and nuts. * **Shafts and Spindles:** For furnace conveyors and heat treatment equipment. * **Valve Components:** Valve stems, seats, and trim in severe service valves. * **Pump Parts:** Shafts and internals for high-temperature pumps. * **Billets for Forgings:** Used to create custom forged parts like turbine rings. * **Flat Bar Applications:** * **Structural Supports:** Brackets, beams, and rails within industrial furnaces. * **Heat Treating Fixtures:** Tooling for holding parts during heat treatment (e.g., baskets, grids). * **Wear Bars:** Guides and liners in high-temperature environments. * **Fabricated Assemblies:** Base material for welded structures requiring high-temperature integrity. * **Key Industries Served:** * Aerospace (Jet engine components, afterburners) * Industrial Furnace & Heat Treating (Radiant tubes, muffles, trays) * Chemical & Petrochemical Processing (Furnace internals, reformer components) * Power Generation (Gas turbine components) --- **Disclaimer:** *Inconel® is a registered trademark of Special Metals Corporation, a PCC company.
