Key Properties- Outstanding High-Temperature Oxidation & Sulfidation Resistance: Maintains stable performance against oxidation and sulfidation up to 980°C (1800°F), ideal for long-term exposure to high-temperature flue gas and sulfur-containing hot environments.
- Superior Creep & Stress Rupture Strength: Retains reliable mechanical integrity during repeated thermal cycling, resisting permanent deformation under sustained high-temperature load.
- Excellent Corrosion Resistance: Offers robust protection against aggressive sulfur-rich gaseous media and high-temperature corrosive atmospheres.
|  |
Processing & Specification Requirements- Heat Treatment: Solution annealed at approximately 1175°C (2150°F) followed by rapid cooling as required by AMS 5711.
- Fabrication Guidance: TIG welding with strict process control is recommended to prevent material sensitization. Machining should adopt dedicated cutting parameters for nickel-base alloys.
ApplicationsAerospace & Aviation Jet engine combustor components, turbine seals, exhaust assemblies and other hot-section critical parts. Chemical & Thermal Industrial High-temperature chemical processing equipment, furnace hardware, high-temperature reactor components working in corrosive gas environments.
