### **Product Introduction: Alloy HX / Inconel HX (UNS N06002)** #### **Overview** **Alloy HX** (commercially known as **Inconel® HX**) is a nickel-chromium-iron-molybdenum alloy designed for exceptional high-temperature strength and outstanding resistance to oxidizing and reducing atmospheres. This solid-solution strengthened superalloy maintains excellent mechanical properties and structural stability at temperatures up to 1200°C (2200°F), making it particularly suitable for extreme temperature applications in heat treatment, industrial furnace, and chemical processing industries. The alloy exhibits outstanding resistance to carburization and oxidation, coupled with good ductility and fabricability, enabling its use in the most demanding high-temperature environments. --- #### **Chemical Composition** The chemical composition of Alloy HX (UNS N06002) is optimized for high-temperature performance: | Element | Content (%) | |---------|-------------| | **Nickel (Ni)** | 47.0 | | **Chromium (Cr)** | 22.0 | | **Iron (Fe)** | 18.0 | | **Molybdenum (Mo)** | 9.0 | | **Cobalt (Co)** | 1.5 | | **Tungsten (W)** | 0.6 | | **Carbon (C)** | 0.10 | | **Manganese (Mn)** | 1.00 | | **Silicon (Si)** | 0.50 | | **Phosphorus (P)** | 0.040 | | **Sulfur (S)** | 0.030 | *Note: The alloy derives its strength from solid solution strengthening mechanism, with balanced composition providing optimal high-temperature performance.* --- #### **Physical Properties** Critical properties for high-temperature design applications: | Property | Metric Value | Imperial Value | |----------|--------------|----------------| | **Density** | 8.22 g/cm³ | 0.297 lb/in³ | | **Melting Range** | 1330 - 1380 °C | 2425 - 2515 °F | | **Specific Heat (20°C)** | 448 J/kg·K | 0.107 Btu/lb·°F | | **Thermal Conductivity (20°C)** | 11.2 W/m·K | 77.8 Btu·in/hr·ft²·°F | | **Thermal Expansion Coefficient (20-100°C)** | 12.6 μm/m·°C | 7.0 μin/in·°F | | **Modulus of Elasticity** | 212 GPa | 30.7 x 10⁶ psi | | **Electrical Resistivity** | 1.18 μΩ·m | - | --- #### **Mechanical Properties** Typical mechanical properties at room temperature: **Annealed Condition:** * **Ultimate Tensile Strength:** 690-860 MPa (100-125 ksi) * **Yield Strength (0.2% Offset):** 310-480 MPa (45-70 ksi) * **Elongation:** 40-50% * **Hardness:** 70-90 HRB **Elevated Temperature Performance:** * **0.2% Yield Strength at 980°C (1800°F):** ≥ 55 MPa (8 ksi) * **Stress Rupture Strength:** Excellent long-term performance at high temperatures * **Creep Resistance:** Maintains integrity under sustained load at elevated temperatures --- #### **International Standards** Alloy HX is covered by numerous international specifications: **ASTM Standards:** * **ASTM B435:** UNS N06002 Plate, Sheet, and Strip * **ASTM B572:** UNS N06002 Rod * **ASTM B619:** UNS N06002 Welded Pipe **ASME Standards:** * **ASME SB435:** Plate, Sheet, and Strip * **ASME SB572:** Rod and Bar **Other International Standards:** * **ISO 6207:** Nickel and nickel alloy tubes * **DIN 17742:** Wrought nickel-chromium-iron alloys * **GB/T 15008:** Chinese standard for corrosion-resistant alloys --- #### **Product Applications** Alloy HX serves in extreme high-temperature applications across various industries: **Heat Treatment Industry:** * **Furnace Components:** Radiant tubes, retorts, muffles * **Heat Treatment Fixtures:** Baskets, trays, fixtures * **Annealing Equipment:** Covers, inner covers, cooling systems **Chemical Processing:** * **Reformer Units:** Catalyst support grids, internals * **Ethylene Production:** Cracked gas transfer line exchangers * **Syngas Production:** Waste heat boiler components **Power Generation:** * **Heat Recovery Systems:** Boiler components, ducting * **Gas Turbines:** Combustion chamber parts * **Waste Incineration:** Superheater tubes, support systems **Industrial Furnaces:** * **Ceramic Industry:** Kiln furniture, setters * **Glass Manufacturing:** Processing equipment components * **Steel Production:** Heat treatment furnace components --- #### **Key Advantages** * **Exceptional High-Temperature Strength:** Maintains properties up to 1200°C (2200°F) * **Outstanding Oxidation Resistance:** Excellent resistance to scaling in oxidizing atmospheres * **Good Carburization Resistance:** Performs well in carburizing environments * **Excellent Thermal Stability:** Maintains structural integrity under thermal cycling * **Good Fabricability:** Can be welded, formed, and machined using standard methods * **Resistance to Reducing Atmospheres:** Performs well in both oxidizing and reducing conditions * **Long Service Life:** Provides extended component life in high-temperature applications * **Proven Reliability:** Established track record in demanding applications **Heat Treatment:** * **Annealing Temperature:** 1175-1205°C (2150-2200°F) * **Rapid Cooling:** Water quenching or rapid air cooling * **Stress Relieving:** 870-900°C (1600-1650°F) as required **Quality Assurance:** * **Chemical Analysis:** Complete composition verification * **Mechanical Testing:** Tensile, hardness, and impact testing * **High-Temperature Testing:** Stress rupture and creep testing * **Non-Destructive Testing:** PT, UT, RT as specified **Note:** *Inconel® is a registered trademark of Special Metals Corporation.
