3.Key Features & Advantages
- Precipitation Hardenable High Strength: Achieves tensile strength exceeding 1170 MPa after solution annealing and double aging treatment, superior to many solid-solution alloys in its class.
- Excellent High-Temperature Performance: Maintains structural integrity and mechanical properties up to 700°C (1292°F), ideal for gas turbine hot-section components.
- Superior Oxidation Resistance: Forms a stable chromium oxide protective layer, providing long-term oxidation resistance up to 980°C (1796°F).
- Stress-Corrosion Cracking Resistance: Outstanding resistance to chloride-induced stress-corrosion cracking in high-temperature aqueous environments.
- Excellent Relaxation Resistance: Maintains clamping force at elevated temperatures, critical for spring and fastener applications in aerospace and nuclear systems.
- Multi-National Standard Compliance: Certified to GB, AMS, ASTM, DIN, AFNOR, BS, and JIS standards, enabling global sourcing and deployment.
4.Typical Applications
- Aerospace: Jet engine seals, turbine blades, rotors, shafts, afterburner components, thrust reverser assemblies.
- Gas Turbine: Combustion chamber components, transition ducts, diffuser casings, bolting and fasteners.
- Nuclear Reactors: Control rod drive springs, hold-down springs, core support structures, reactor vessel internals.
- Rocket Engines: Thrust chambers, injector plates, nozzle components for liquid-fueled rocket engines.
- Heat Exchangers: High-temperature tubular heat exchangers in chemical processing and petrochemical plants.
- Industrial Springs: High-temperature springs, fasteners, and bolting for furnace components and heat treatment fixtures.
