### **Product Introduction: Astroloy M (UNS N13017) Rod** **Astroloy M (UNS N13017) Rod** is a high-performance nickel-based superalloy product form, supplied in a consolidated bar form suitable for machining critical components. Produced via advanced Powder Metallurgy (PM) processing, typically followed by Hot Isostatic Pressing (HIP) and often extrusion or forging, this rod stock offers a homogeneous, fine-grained microstructure essential for achieving the alloy's ultimate mechanical properties. This product form is the starting material for manufacturing the most demanding rotating parts in gas turbine engines. Astroloy M Rod provides the exceptional high-temperature strength, creep resistance, and microstructural stability required for applications where conventional wrought alloys are insufficient. --- #### **Key Features & Advantages** * **Ultra-High Temperature Strength:** Maintains exceptional tensile, creep, and stress-rupture properties at temperatures up to **980°C (1800°F)**. * **Superior Microstructural Homogeneity:** The PM+HIP manufacturing process eliminates the chemical segregation found in cast alloys, resulting in uniform properties and enhanced reliability. * **Excellent Structural Integrity:** The rod form provides a sound, consolidated billet that is ideal for subsequent machining, grinding, or even isothermal forging into near-net-shape components. * **Optimized for High-Stress Applications:** Delivers an outstanding combination of high strength and good fatigue resistance, which is critical for rotating parts under centrifugal loads. * **Controlled Grain Structure:** The processing route allows for a controlled grain size that is optimized for both strength and damage tolerance. --- #### **Chemical Composition (Typical Weight %)** The composition is meticulously balanced to maximize gamma prime (γ') precipitation strengthening. | Element | Content (%) | Element | Content (%) | | :--- | :--- | :--- | :--- | | **Nickel (Ni)** | Balance | **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 | | **Carbon (C)** | 0.02 - 0.06 | **Boron (B)** | 0.015 - 0.030 | | **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 | --- #### **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 (20-100°C)** | ~12.8 μm/m·°C | ~7.1 x10⁻⁶ in/in·°F | | **Modulus of Elasticity (Room Temperature)** | ~210 GPa | ~30.5 x 10⁶ psi | | **Thermal Conductivity** | Low (~11.5 W/m·K at 100°C) | ~80 Btu·in/hr·ft²·°F | --- #### **Mechanical Properties (Typical for HIPed + Heat-Treated Rod)** *Properties are achieved through a specific solution and aging heat treatment after consolidation.* | Property | 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 % | | **Reduction of Area** | 12 - 25 % | 12 - 25 % | | **Creep Rupture Strength** | Excellent at 730°C - 980°C | Excellent at 1350°F - 1800°F | --- #### **International Standards** Astroloy M Rod is produced under the most stringent aerospace specifications. * **AMS 6306:** The primary Aerospace Material Specification for "Bars, Forgings, and Rings, Powder Metallurgy Nickel-Base Superalloy." This standard defines the requirements for PM consolidated billet and rod. * **UNS N13017:** The Unified Numbering System designation. * **OEM Proprietary Specifications:** This material is often procured to detailed internal specifications from major engine manufacturers like **GE Aviation, Rolls-Royce, and Pratt & Whitney**, which dictate strict controls on powder quality, consolidation, and heat treatment. --- #### **Product Applications** Astroloy M Rod is exclusively used for machining the most critical rotating components in the aerospace industry. * **Aerospace Gas Turbine Engines:** * **High-Pressure Turbine (HPT) Disks and Hubs:** The primary application, where the rod is machined into rotors that operate under extreme centrifugal stress at peak temperatures. * **Compressor Disks (Rear Stages):** For the hottest, highest-stress sections of the high-pressure compressor. * **Turbine Shafts and Spools:** Critical rotating structures that transmit power from the turbine to the compressor. * **Blisk (Bladed Disk) Pre-forms:** The rod can be used as a starting material for isothermal forging of blisks. --- **Disclaimer:** *Astroloy is a trademark associated with high-performance alloy manufacturers. The information provided is for descriptive purposes. Astroloy M is a critically sensitive material, and its final properties are entirely dependent on its specific PM processing and heat treatment. For design and procurement, it is mandatory to adhere to the relevant AMS and/or OEM proprietary specifications.*
