**Product Introduction: FM-82 Forgings / UNS N06082** **Overview** FM-82 Forgings are high-performance components manufactured through controlled forging processes from nickel-chromium-molybdenum-niobium alloy UNS N06082. The forging process enhances the material's mechanical properties by refining the grain structure and improving directional strength, making these components ideal for critical applications in corrosive and high-temperature environments where reliability and structural integrity are paramount. **Key Characteristics** - Enhanced mechanical properties through grain refinement - Superior structural integrity with minimal internal defects - Excellent corrosion resistance in oxidizing and reducing environments - High-temperature strength and oxidation resistance up to 1100°C - Improved fatigue and creep resistance - Homogeneous microstructure with consistent properties - Good machinability in heat-treated condition --- **Chemical Composition (Weight %)** | Element | Content (%) | |------------------|-----------------| | Nickel (Ni) | Balance | | Chromium (Cr) | 18.0 - 22.0 | | Iron (Fe) | ≤ 3.0 | | Molybdenum (Mo) | 2.0 - 4.0 | | Niobium (Nb) | 1.5 - 4.0 | | Titanium (Ti) | ≤ 1.0 | | Manganese (Mn) | ≤ 1.0 | | Silicon (Si) | ≤ 0.75 | | Carbon (C) | ≤ 0.10 | | Phosphorus (P) | ≤ 0.03 | | Sulfur (S) | ≤ 0.015 | --- **Physical Properties** | Property | Value | |-------------------------------|---------------------------| | Density | 8.28 g/cm³ (0.299 lb/in³) | | Melting Range | 1350-1400°C (2460-2550°F) | | Thermal Conductivity | 10.1 W/m·K (at 100°C) | | Specific Heat Capacity | 430 J/kg·K (at 20°C) | | Electrical Resistivity | 1.18 μΩ·m | | Coefficient of Thermal Expansion | 13.5 × 10⁻⁶/°C (20-300°C) | | Modulus of Elasticity | 205 GPa (29.7 × 10⁶ psi) | --- **Mechanical Properties (Solution Annealed & Aged)** | Property | Room Temperature | 650°C (1200°F) | |---------------------------|-------------------------|----------------------| | Tensile Strength | 720-800 MPa (104-116 ksi) | 500-580 MPa (73-84 ksi) | | Yield Strength (0.2% Offset) | 350-420 MPa (51-61 ksi) | 290-350 MPa (42-51 ksi) | | Elongation | 35-45% | 25-35% | | Reduction of Area | 40-50% | 30-40% | | Impact Strength (Charpy V) | 80-120 J | 60-90 J | | Hardness (Brinell) | 180-230 HB | - | --- **Product Applications** **Chemical Processing Industry** - High-pressure valve bodies and components - Pump casings and impellers - Reactor vessel components - Agitator shafts and mixing elements - Heat exchanger forgings **Power Generation** - Turbine blades and disks - Compressor wheels - Generator components - High-temperature fasteners - Nuclear reactor core components **Oil and Gas Industry** - Wellhead components - Christmas tree forgings - Downhole tool components - Valve trims and bodies - Pipeline forgings **Aerospace and Defense** - Jet engine components - Rocket motor parts - Missile components - Structural airframe parts **Marine Applications** - Propeller shafts - Marine engine components - Subsea equipment forgings - Naval vessel components --- **International Standards & Specifications** **ASTM Standards** - ASTM B564: Standard Specification for Nickel Alloy Forgings - ASTM B166: Standard Specification for Nickel-Chromium-Iron Alloys Rod, Bar, and Wire **ASME Standards** - ASME SB-564: Nickel Alloy Forgings - ASME Section III: Nuclear Facility Components - ASME Section VIII: Pressure Vessels **Aerospace Standards** - AMS 5666: Nickel Alloy, Corrosion and Heat-Resistant, Bars, Forgings, and Rings **European Standards** - EN 10204: Metallic Products - Types of Inspection Documents - EN 10095: Heat Resisting Steels and Nickel Alloys **Quality Standards** - ISO 9001: Quality Management Systems - ISO 14001: Environmental Management Systems - PED 2014/68/EU: Pressure Equipment Directive --- **Forging Process & Quality Assurance** **Manufacturing Process** - Open-die forgings for large components - Closed-die forgings for complex shapes - Ring-rolled forgings for circular components - Press forgings for high-volume production **Heat Treatment** - Solution Annealing: 1150-1200°C (2100-2190°F) - Quenching: Water or rapid air cool - Aging Treatment: 720-760°C (1328-1400°F) - Stress Relieving: As required for specific applications **Quality Control** - Ultrasonic Testing per ASTM A388 - Liquid Penetrant Testing per ASTM E165 - Magnetic Particle Testing per ASTM E709 - Radiographic Testing as required - Chemical Analysis Verification - Mechanical Testing from representative samples **Certification Requirements** - Material Traceability from Melt to Final Product - Heat Treatment Records and Charts - Non-Destructive Testing Reports - Dimensional Inspection Reports - Mechanical Test Certificates - Compliance Certificates to Applicable Standards --- **Note** FM-82 Forgings offer superior mechanical properties compared to cast or wrought products due to the refined grain structure achieved through controlled deformation processes. The forging orientation should be considered in design to maximize mechanical properties in critical stress directions. Proper heat treatment is essential to achieve optimal combination of strength, ductility, and corrosion resistance. **Disclaimer** The information provided is for reference purposes. Actual properties may vary based on forging size, shape, and specific heat treatment parameters. For critical applications, consult the forging manufacturer's technical data and conduct appropriate qualification testing. All forgings should be designed, manufactured, and implemented in accordance with relevant industry standards and manufacturer recommendations.
