Key Characteristics of Nimonic 95
Superior High-Temperature Creep Strength: Exhibits exceptional resistance to creep deformation and rupture at temperatures up to 980°C, making it ideal for long-term load-bearing components in high-heat environments.
Excellent Fatigue Resistance: Maintains structural integrity under cyclic thermal and mechanical stress, critical for components like turbine discs and blades that experience repeated temperature fluctuations.
Precipitation-Hardenable: Achieves peak mechanical properties through a controlled heat treatment process (solution annealing at 1080 - 1120°C, followed by aging at 700 - 760°C), enhancing tensile strength and hardness.
Strong Oxidation Resistance: Forms a dense, adherent oxide layer at elevated temperatures, resisting scaling and oxidation in air and combustion gas environments up to 1000°C.
Good Corrosion Resistance: Performs well in mildly corrosive environments, including industrial atmospheres and low-concentration acidic/alkaline media, complementing its high-temperature capabilities.
Reliable Fabricability: Can be forged, rolled, and machined with appropriate tooling (using heat-resistant alloy cutting tools); welding is feasible with TIG/MIG processes, though post-weld heat treatment is recommended to restore mechanical properties.
Applications of Nimonic 95
Aerospace Industry: Turbine discs, compressor blades, and combustion chamber liners for jet engines and rocket propulsion systems, where creep resistance and fatigue stability are paramount.
Power Generation: High-pressure turbine blades, rotor components, and steam pipe fittings for gas and steam turbines, ensuring reliable operation in high-temperature power cycles.
Industrial Turbomachinery: Blades and discs for industrial gas turbines used in oil refining, petrochemical processing, and waste-to-energy plants.
Nuclear Industry: Components for advanced nuclear reactors (e.g., fast breeder reactors) that require resistance to high temperatures and radiation-induced degradation.
High-Temperature Furnaces: Heating elements, furnace liners, and support structures for industrial furnaces operating at temperatures above 900°C.
Fasteners and Structural Components:High-stress bolts, nuts, and brackets for aerospace and power generation equipment, where strength and stability at elevated temperatures are non-negotiable.
