**Technical Data Sheet: Udimet Alloy R41 Plate (UNS N07041)** **1.0 Product Overview** Udimet Alloy R41 Plate (UNS N07041) is a premium precipitation-hardenable nickel-chromium-cobalt superalloy supplied in plate form. This high-strength material is specifically engineered to maintain exceptional mechanical properties and oxidation resistance at elevated temperatures up to 980°C (1800°F). The plate product form is ideal for fabricating large structural components requiring excellent strength-to-weight ratio and outstanding performance in extreme thermal and corrosive environments. **2.0 Chemical Composition** | Element | Content (%) | Primary Function | |---------|-------------|------------------| | Ni | Balance | Austenitic Matrix | | Cr | 18.0-20.0 | Oxidation/Corrosion Resistance | | Co | 10.0-12.0 | Solid Solution Strengthening | | Mo | 9.0-10.5 | Solid Solution Strengthening | | Ti | 3.0-3.5 | Gamma Prime Former (Ni₃Ti) | | Al | 1.4-1.8 | Gamma Prime Former (Ni₃Al) | | Fe | 5.0 max | - | | C | 0.06-0.12 | Carbide Formation | | B | 0.003-0.010 | Grain Boundary Strengthening | | Si | 0.50 max | - | | Mn | 0.50 max | - | | Cu | 0.50 max | - | **3.0 Physical Properties** | Property | Metric Value | Imperial Value | Condition | |----------|--------------|----------------|-----------| | Density | 8.25 g/cm³ | 0.298 lb/in³ | Room Temperature | | Melting Range | 1320-1410°C | 2410-2570°F | - | | Electrical Resistivity | 1.23 μΩ·m | 48.6 μΩ·in | 21°C | | Thermal Conductivity | 10.7 W/m·K | 74.0 Btu·in/(hr·ft²·°F) | 21°C | | Mean Coefficient of Thermal Expansion | 13.5 × 10⁻⁶/°C | 7.5 × 10⁻⁶/°F | 20-650°C | | Modulus of Elasticity | 216 GPa | 31.4 × 10⁶ psi | Room Temperature | **4.0 Mechanical Properties** **4.1 Typical Room Temperature Properties (Solution Annealed & Aged)** - Tensile Strength: 1240-1380 MPa (180-200 ksi) - Yield Strength (0.2% Offset): 1035-1140 MPa (150-165 ksi) - Elongation: 10-20% - Reduction in Area: 15-25% - Hardness: 36-42 HRC **4.2 Elevated Temperature Capability** - Excellent creep rupture strength up to 980°C (1800°F) - Maintains 75% of room temperature strength at 870°C (1600°F) - Outstanding fatigue resistance under thermal cycling conditions **5.0 Heat Treatment** - **Solution Annealing:** 1065-1080°C (1950-1975°F), rapid air cool or faster - **Aging Treatment:** 760°C/16 hours + 650°C/16 hours (1400°F/16h + 1200°F/16h) - **Stress Relieving:** Available for welded fabrications **6.0 Product Applications** **6.1 Aerospace & Defense** - Jet engine structural mounts and frames - Afterburner components and liners - Missile body sections and skins - Rocket motor casings and supports - Aircraft hot structure components **6.2 Power Generation** - Gas turbine combustor liners - Heat shield plates - Turbine exhaust components - Nuclear reactor core support structures **6.3 Industrial Processing** - High-temperature furnace components - Heat treatment fixtures and trays - Chemical reactor vessels and liners - Pyroprocessing equipment structural parts **7.0 International Standards & Specifications** | Standard Organization | Standard Number | Description | |----------------------|-----------------|-------------| | ASTM International | ASTM B637 | Precipitation-Hardening Nickel Alloy Plate | | AMS | AMS 5545 | Sheet, Strip, and Plate | | ASME | SB637 | Boiler and Pressure Vessel Code | | DIN | DIN 17752 | Nickel Alloy Plate and Sheet | | UNS | N07041 | Unified Numbering System | | Werkstoff Nr. | 2.4972 | German Material Number | **8.0 Available Plate Specifications** - **Thickness Range:** 0.5 mm to 150 mm (0.020" to 6") - **Width Range:** Up to 1500 mm (60 inches) - **Length Range:** Up to 4000 mm (160 inches) - **Surface Finish:** Hot-rolled, cold-rolled, annealed, or pickled **9.0 Fabrication Characteristics** **9.1 Machining** - Best performed in solution-annealed condition - Requires rigid machine tools and positive rake angles - Recommended use of carbide or ceramic cutting tools - Adequate cooling and chip clearance essential **9.2 Welding** - Weldable using GTAW and GMAW processes - Matching filler metals (ERNiCrMo-XX series) recommended - Pre-heat and post-weld heat treatment required - Suitable for repair and fabrication welding **9.3 Forming** - Good formability in solution-annealed condition - Can be cold formed with appropriate tooling - Hot forming possible at 1040-1175°C (1900-2150°F) - Springback considerations required for precision forming **10.0 Quality Assurance** - Ultrasonic testing per ASTM A578 for internal quality - Dye penetrant or magnetic particle inspection available - Full traceability from melt to finished plate - Certification to EN 10204 3.2 or equivalent standards - Microstructure and grain size control **11.0 Corrosion Resistance** - Outstanding oxidation resistance to 980°C (1800°F) - Excellent resistance to hot corrosion and sulfidation - Good performance in carburizing and nitriding atmospheres - Maintains integrity in thermal cycling environments Udimet Alloy R41 Plate offers unparalleled performance for critical high-temperature structural applications where conventional materials prove inadequate.
