### **Product Introduction: Astroloy M (UNS N13017) Bar - Round Bar & Flat Bar** **Astroloy M (UNS N13017) Bar** represents the premium-grade nickel-based superalloy supplied in consolidated bar form, including both round bars and flat bars, manufactured through advanced Powder Metallurgy (PM) processing routes. This product form serves as the fundamental starting material for machining mission-critical components that operate under extreme conditions where conventional alloys fail. Produced via Hot Isostatic Pressing (HIP) followed by thermomechanical processing, Astroloy M bars offer exceptional microstructural homogeneity and directional properties. The round bar configuration is ideal for rotating components, while flat bars provide optimal material utilization for structural supports and non-rotating applications requiring the same superior performance characteristics. --- #### **Key Features & Advantages** * **Exceptional High-Temperature Capability**: Maintains outstanding mechanical properties including tensile strength, creep and stress-rupture resistance at temperatures up to 980°C (1800°F) * **Superior Microstructural Control**: PM processing ensures fine, uniform microstructure free from chemical segregation, enhancing reliability and property consistency * **Optimized Mechanical Characteristics**: Combination of high strength with adequate ductility and fatigue resistance critical for rotating and stationary components * **Enhanced Production Versatility**: Available in round bars for rotational symmetry applications and flat bars for structural components * **Excellent Thermal Stability**: Maintains property integrity after prolonged exposure to extreme operating temperatures --- #### **Chemical Composition (Typical Weight %)** | 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** | 12.8 μm/m·°C (20-100°C) | 7.1 × 10⁻⁶ in/in·°F | | **Modulus of Elasticity** | 210 GPa | 30.5 × 10⁶ psi | | **Thermal Conductivity** | 11.5 W/m·K (100°C) | 80 Btu·in/hr·ft²·°F | --- #### **Mechanical Properties (Typical for HIPed + Heat-Treated Condition)** | 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 (980°C/1800°F)** | Excellent | Excellent | --- #### **International Standards** * **AMS 6306**: Primary specification for "Bars, Forgings, and Rings, Powder Metallurgy Nickel-Base Superalloy" * **UNS N13017**: Unified Numbering System designation * **OEM Specifications**: Compliant with major engine manufacturers' proprietary standards (GE, Rolls-Royce, Pratt & Whitney) * **NADCAP**: Manufacturing processes comply with NADCAP accreditation requirements for special processes --- #### **Product Applications** **Round Bar Applications:** - High-pressure turbine disks and rotors - Compressor disks (rear stages) - Turbine shafts and spools - Blisk (bladed disk) pre-forms - Rotating seals and bushings **Flat Bar Applications:** - Turbine structural supports and brackets - Combustion chamber mounting components - Nozzle guide vane segments - Stationary seal segments - Repair and overlay substrates --- **Disclaimer:** *Astroloy is a trademark associated with various high-performance alloy manufacturers.
