### **Product Introduction: Astroloy M (UNS N13017) Wire** **Astroloy M (UNS N13017)** is a premium, powder metallurgy (PM) nickel-based superalloy specifically designed for exceptional high-temperature strength, creep resistance, and structural stability. The "M" designation often refers to a modified or specific manufacturing process that enhances its workability and consistency. When supplied in wire form, Astroloy M is used for the most demanding applications, primarily as a filler metal for welding and for additive manufacturing (3D printing) of high-integrity components. This alloy retains a significant portion of its strength at temperatures up to 980°C (1800°F), making it a critical material for the hottest sections of modern gas turbine engines. The wire product is characterized by its precise chemistry, smooth surface finish, and consistent diameter, which are essential for automated welding and deposition processes. --- #### **Key Features & Advantages** * **Exceptional High-Temperature Strength:** Offers superior tensile, creep, and stress-rupture properties compared to many conventional wrought superalloys like INCONEL 718. * **Outstanding Microstructural Stability:** Maintains its mechanical properties and resistance to phase precipitation after long-term exposure to high temperatures. * **Excellent Weldability (as a Filler Metal):** Designed for joining similar and dissimilar nickel-based superalloys where the weld metal must match the base metal's high-temperature performance. * **Solution and Precipitation Strengthened:** Strengthened by a high volume fraction of gamma prime (γ') precipitates, enabled by its high aluminum and titanium content. * **Critical for Additive Manufacturing:** Wire is a key feedstock for Wire Arc Additive Manufacturing (WAAM) and other directed energy deposition (DED) processes to produce large, complex near-net-shape components. --- #### **Chemical Composition (Typical Weight %)** The composition of Astroloy M is tightly controlled to achieve its unique properties. | Element | Content (%) | Element | Content (%) | | :--- | :--- | :--- | :--- | | **Nickel (Ni)** | Bal. | **Molybdenum (Mo)** | 4.5 - 5.5 | | **Chromium (Cr)** | 14.0 - 16.0 | **Aluminum (Al)** | 4.0 - 4.5 | | **Cobalt (Co)** | 16.0 - 18.0 | **Titanium (Ti)** | 3.4 - 3.8 | | **Molybdenum (Mo)** | 4.5 - 5.5 | **Boron (B)** | 0.015 - 0.030 | | **Carbon (C)** | 0.02 - 0.06 | **Zirconium (Zr)** | 0.025 - 0.050 | | **Iron (Fe)** | ≤ 0.50 | **Manganese (Mn)** | ≤ 0.10 | | **Silicon (Si)** | ≤ 0.10 | **Sulfur (S)** | ≤ 0.015 | | **Copper (Cu)** | ≤ 0.10 | | | *Note: The high combined Al+Ti content ( > 6.5%) is responsible for the extensive gamma prime precipitation.* --- #### **Physical Properties** | Property | Metric Unit | Imperial Unit | | :--- | :--- | :--- | | **Density** | ~8.0 g/cm³ | ~0.289 lb/in³ | | **Melting Range** | ~1330 - 1380 °C | ~2425 - 2515 °F | | **Thermal Expansion Coefficient** | 12.8 μm/m·°C (20-100°C) | 7.1 x10⁻⁶ in/in·°F (68-212°F) | | **Modulus of Elasticity** | ~210 GPa (at room temperature) | ~30.5 x 10⁶ psi | *Note: Physical properties for PM alloys can vary based on the specific consolidation and processing route.* --- #### **Mechanical Properties (Typical for Wrought or HIPed Form)** *Mechanical properties for the wire itself are not typically published, as its performance is defined by the weld deposit or AM-built structure. The following are representative of the fully heat-treated Astroloy M material.* | Property (at Room Temperature) | Value (Metric) | Value (Imperial) | | :--- | :--- | :--- | | **Tensile Strength, Ultimate** | 1400 - 1600 MPa | 203 - 232 ksi | | **Tensile Strength, Yield (0.2% Offset)** | 1100 - 1300 MPa | 160 - 189 ksi | | **Elongation at Break** | 10 - 20 % | 10 - 20 % | | **Creep Rupture Strength (980°C / 1800°F)** | Excellent, specific values are application-dependent. | | --- #### **International Standards** Astroloy M is covered by several aerospace and industry-specific standards. * **AMS specifications:** While a direct public AMS for "Astroloy M Wire" may be proprietary, the alloy falls under the umbrella of several PM superalloy specifications. Key related standards include: * **AMS 6306:** For PM Superalloy Forgings (covers the base material). * **Customer-Specific Specifications:** Often, the wire is produced to an engine manufacturer's or end-user's proprietary specification (e.g., Rolls-Royce, GE, Pratt & Whitney). * **UNS N13017:** Unified Numbering System designation for this specific composition. * **Aerospace Material Specifications (Internal):** Major OEMs have their own internal material codes for Astroloy M wire used in repair and manufacturing. --- #### **Product Applications** Astroloy M Wire is exclusively used in the most critical, high-stress, high-temperature applications, primarily within the aerospace and power generation industries. * **Aerospace & Defense:** * **Welding & Repair:** Used as a filler metal for Gas Tungsten Arc Welding (GTAW/TIG) and Plasma Transferred Arc (PTA) welding to repair and join turbine blades, vanes, and disks in high-pressure turbine sections. * **Additive Manufacturing:** Serves as feedstock for Wire-Arc Additive Manufacturing (WAAM) to produce large, complex components like turbine casings, structural supports, and pre-forms for forging. * **Power Generation:** * **Industrial Gas Turbines:** Repair and overlay of blades, buckets, and nozzles in land-based turbines for peak efficiency. * **High-Performance Racing:** * **Turbocharger Components:** Used in the manufacturing and repair of extreme-duty turbocharger turbines. --- **Disclaimer:** *Astroloy is a trademark of a number of companies, including Carpenter Technology Corporation.
