### **Waspaloy (UNS N07001) - Technical Datasheet** #### **1. Overview** Waspaloy (registered trademark of United Technologies Corp.) is a precipitation-hardenable, nickel-based superalloy renowned for its exceptional strength and corrosion resistance at high temperatures. Designated as **UNS N07001**, it retains its mechanical properties up to approximately 980°C (1800°F), making it a critical material for demanding aerospace and industrial applications. It is available in various forms, including bar, wire, sheet, plate, forgings, and notably, seamless tubes. #### **2. Chemical Composition** The high-temperature performance of Waspaloy is achieved through a careful balance of solid-solution strengthening elements (Chromium, Cobalt, Molybdenum) and precipitation hardening elements (Aluminum, Titanium). | Element | Content (%) | | :--- | :--- | | **Nickel (Ni)** | Balance (approx. 58%) | | **Chromium (Cr)** | 19.00 - 21.00 | | **Cobalt (Co)** | 12.00 - 15.00 | | **Molybdenum (Mo)**| 3.50 - 5.00 | | **Aluminum (Al)** | 1.20 - 1.60 | | **Titanium (Ti)** | 2.75 - 3.25 | | **Iron (Fe)** | ≤ 2.00 | | **Manganese (Mn)** | ≤ 1.00 | | **Silicon (Si)** | ≤ 1.00 | | **Carbon (C)** | 0.02 - 0.10 | | **Boron (B)** | 0.003 - 0.010 | | **Zirconium (Zr)** | ≤ 0.070 | | **Copper (Cu)** | ≤ 0.50 | | **Sulfur (S)** | ≤ 0.030 | #### **3. Physical Properties** | Property | Value | | :--- | :--- | | **Density** | 8.22 g/cm³ (0.297 lb/in³) | | **Melting Point** | ~ 1330 - 1360 °C (2425 - 2480 °F) | | **Thermal Expansion Coefficient** | 12.6 μm/m·°C (20-100°C) | | **Thermal Conductivity** | 11.2 W/m·K (at 100°C) | | **Specific Heat** | 420 J/kg·K (at 20°C) | | **Electrical Resistivity** | 1.26 μΩ·m | | **Modulus of Elasticity** | 214 GPa (31 x 10⁶ psi) | #### **4. Mechanical Properties (Typical for Annealed & Aged Condition)** Properties can vary with product form and heat treatment. The following are typical for bar and forgings. * **Tensile Strength:** ≥ 1240 MPa (180 ksi) * **Yield Strength (0.2% Offset):** ≥ 795 MPa (115 ksi) * **Elongation:** ≥ 15% * **Reduction of Area:** ≥ 18% * **Hardness:** ≥ 34 HRC #### **5. Waspaloy Tube** Waspaloy is extensively used to manufacture **seamless tubes** through processes like extrusion and pilgering. These tubes are essential for applications requiring high strength, pressure integrity, and corrosion resistance in high-temperature environments. **Key Features of Waspaloy Tubes:** * **Excellent Creep Rupture Strength:** Can withstand constant high stress at elevated temperatures. * **Oxidation Resistance:** Forms a protective chromium oxide scale. * **Thermal Fatigue Resistance:** Withstands repeated heating and cooling cycles. * **Good Fabricability:** Can be bent and formed, though it requires more power than stainless steels. #### **6. Product Applications** Waspaloy's primary use is in the hot sections of gas turbine engines and other high-performance machinery. * **Aerospace:** * Turbine blades and disks * Compressor seals, shafts, and spacers * High-strength fasteners * Combustion chamber components * **Industrial Gas Turbines:** * Turbine wheels, blades, and bolts * **Oil & Gas:** * Downhole tooling for high-temperature/high-pressure (HTHP) wells * Valve components * Fasteners for subsea equipment * **Nuclear Power:** * High-strength bolting * **Waspaloy Tube-Specific Applications:** * Heat exchanger tubing in high-temperature service * Instrumentation and thermocouple tubing in hot sections of engines * Tubing for high-pressure hydraulic and fuel systems #### **7. International Standards** Waspaloy is covered by numerous international standards, which specify requirements for chemical composition, mechanical properties, and heat treatment. **Aerospace (Most Common):** * **AMS (Aerospace Material Specification):** * **AMS 5708:** Bar, forgings, and rings (Solution Treated and Aged) * **AMS 5709:** Bar, forgings, and rings (Annealed) * **AMS 5828:** Welding wire * **AMS 5544:** Sheet, strip, and plate **ASTM / ASME:** * **ASTM B637:** Standard Specification for Precipitation-Hardening Nickel Alloy Bars, Forgings, and Forging Stock for High-Temperature Service. * **ASME SB637:** Equivalent to ASTM B637 for ASME Boiler and Pressure Vessel Code applications. **European & Others:** * **ISO 9724:** Nickel-cobalt-chromium-molybdenum alloy bars (covers Waspaloy) * **EN 10204:** Type 3.1/3.2 Inspection Certificates * **U.S. Military:** **MIL-S-25043** (Shafting, Turbine Engine, High-Temperature Steel and Alloy) **Standards for Waspaloy Tube:** * **AMS 5581:** Seamless Tube, Corrosion and Heat-Resistant, Nickel Alloy (Waspaloy) * **ASTM B622 / ASME SB622:** Standard Specification for Seamless Nickel and Nickel-Cobalt Alloy Pipe and Tube. --- **Disclaimer:** The information provided here is for general reference purposes.
