Product Description
Nimonic 75 High Temperature Alloy Bar - Extreme Heat Resistance for Steam Turbine Wheels
Engineered for exceptional strength and oxidation resistance at sustained high temperatures, Nimonic 75 High Temperature Alloy Bar delivers unmatched performance in critical power generation applications. This premium-grade nickel-chromium alloy offers superior creep resistance and thermal stability, making it essential for demanding components in steam turbines, gas turbines, and aerospace propulsion systems.
Composed of 80% nickel, 20% chromium with titanium reinforcement (UNS N06075), the alloy bar maintains outstanding mechanical integrity from ambient temperatures to extreme service conditions exceeding 815°C. Its optimized microstructure ensures unparalleled resistance to thermal fatigue, oxidation, and exhaust gas corrosion, providing reliable long-term operation in high-stress environments where component failure is unacceptable.
Manufactured to stringent AMS 5754/BS HR 505 standards, Nimonic 75 High Temperature Alloy Bar guarantees metallurgical consistency and dimensional precision for forged turbine components. Optimized for hot working, machining, and welding, it is the certified solution for turbine wheels, rotor shafts, and combustion chambers requiring zero deformation at red-hot temperatures and maximum operational lifespan.
Outperforms standard alloys in 815°C+ exhaust gas and steam environments, with oxidation resistance 3X higher than 304 stainless steel.
Maintains 120+ MPa tensile strength at 815°C (1500°F) - from ambient to extreme turbine operating temperatures.
80% Ni-20% Cr-Ti matrix (UNS N06075) prevents sigma phase embrittlement for decade-long service life.
Unique grain boundary design withstands 10,000+ thermal cycles in turbine start-stop operations.
Precision forged into complex turbine geometries with zero cracking at 1100°C+ forming temperatures.
DLX Alloy's Nimonic 75 High Temperature Alloy Bar delivers mission-critical reliability for power generation and aerospace turbine systems. Offering mill-direct pricing, volume discounts for large forging projects, and global logistics with DDP terms, we provide AMS 5754-certified alloy solutions engineered for your extreme heat application requirements.
