Inquiry
Haynes 25 (L605) is a cobalt-nickel-chromium-tungsten alloy renowned for its high-temperature strength, oxidation resistance, and wear resistance. It finds extensive applications in aerospace, medical, energy, and other demanding sectors, serving as a vital material in the production of engine components and artificial joints.
Features
- Excellent high-temperature strength: Maintains structural integrity and mechanical performance under extreme heat.
- Oxidation resistance at 1800°F (980°C): Ideal for components exposed to continuous high-temperature oxidation.
- Wear resistance: Suitable for high-friction environments where material degradation must be minimized.
- Seawater resistance: Performs reliably in marine environments, resisting corrosion caused by prolonged seawater exposure.
Application
- Aerospace industry: Used in gas turbine combustion chambers, jet engine parts, and combustion liners where high strength and oxidation resistance are essential.
- Industrial furnaces: Ideal for mufflers, bushings, and linings in high-temperature kilns and furnace systems.
- Chemical equipment: Applied in reactors and pipeline systems that demand resistance to high-temperature corrosion.
- Marine industry: Suitable for marine turbines and other ocean-exposed components requiring long-term corrosion resistance.
