### **Waspaloy (UNS N07001) & Waspaloy Plate - Technical Datasheet** #### **1. Overview** Waspaloy is a premier, precipitation-hardenable nickel-based superalloy known for its exceptional combination of high tensile strength, creep resistance, and oxidation resistance at temperatures up to 980°C (1800°F). Designated as **UNS N07001**, it is a cornerstone material for the most demanding applications in aerospace and power generation. It is produced in various forms, with **Waspaloy Plate** being critical for large, structural components in hot sections of turbines. #### **2. Chemical Composition** The balance of solid-solution strengtheners and gamma-prime [γ'] formers gives Waspaloy its superior high-temperature properties. | 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 Plate - Solution Annealed and Aged)** Properties are dependent on heat treatment. The following are typical for plate per standards like AMS 5544. * **Tensile Strength:** ≥ 1240 MPa (180 ksi) * **Yield Strength (0.2% Offset):** ≥ 795 MPa (115 ksi) * **Elongation:** ≥ 15% * **Hardness:** ≥ 34 HRC #### **5. Waspaloy Plate** **Waspaloy Plate** refers to flat-rolled product forms typically over 3mm (0.125 inches) in thickness. Plates are supplied in either the annealed (soft) condition for subsequent forming and heat treatment, or in the fully solution treated and aged condition for immediate use. Manufacturing plates from an alloy as strong as Waspaloy requires specialized hot rolling and heat treatment processes. **Key Features of Waspaloy Plates:** * **High Structural Strength:** Provides the backbone for critical components like cases and rings. * **Excellent Creep Rupture Strength:** Maintains integrity under sustained loads at high temperatures. * **Superior Oxidation & Sulfidation Resistance:** The high Chromium content provides a protective scale. * **Good Fabricability:** Can be machined, welded (using appropriate procedures and filler wire like AMS 5828), and formed, though it demands more power than stainless steels. #### **6. Product Applications** Waspaloy's primary use is in the hot sections of gas turbine engines. * **Aerospace:** * **From Plate:** Turbine engine casings, compressor cases, containment rings, shrouds, and structural supports. * **General:** Turbine blades, disks, shafts, spacers, and high-strength fasteners. * **Industrial Gas Turbines (IGT):** * **From Plate:** Casing sections, diaphragms, and transition duct supports. * **General:** Turbine wheels, blades, and bolts. * **Oil & Gas:** * Downhole tooling for high-temperature/high-pressure (HTHP) wells. * Valve components and parts for exposure to sour gas. * **Nuclear Power:** * High-strength bolting. #### **7. International Standards** Waspaloy Plate is covered by several key international standards. **Aerospace (Most Common):** * **AMS (Aerospace Material Specification):** * **AMS 5544:** Sheet, Strip, and Plate (Solution Heat Treated, 1550°F minimum). This is the primary specification for Waspaloy plate. * **AMS 5708:** Bar, Forgings, and Rings (Solution Treated and Aged). Often referenced for mechanical property targets for aged plate. * **AMS 5709:** Bar, Forgings, and Rings (Annealed). For material supplied in the annealed condition. **ASTM / ASME:** * **ASTM B637:** Standard Specification for Precipitation-Hardening Nickel Alloy Bars, Forgings, and Forging Stock for High-Temperature Service. (While focused on bar/forgings, its chemistry and heat treatment are relevant). * **ASME SB637:** Equivalent to ASTM B637 for ASME Boiler and Pressure Vessel Code applications. **European & Others:** * **ISO 9724:** Nickel-cobalt-chromium-molybdenum alloy bars (chemistry reference). * **EN 10204:** Type 3.1/3.2 Inspection Certificates (standard for material certification in Europe). --- **Disclaimer:** The information provided is for general reference.
