ZYTC Alloy is an ISO 9001 and AS 9120B certified superalloy manufacturer and supplier, offering AMS 5660N Alloy 901 bar at factory-direct prices with full material traceability and fast global delivery. AMS5660N specification covers a corrosion- and heat-resistant nickel-iron alloy in the form of bars and forgings up to 5 inches (127 mm) in nominal diameter and forging stock of any size. Alloy 901 (Incoloy® 901 / UNS N09901) is an age-hardenable nickel-iron-chromium superalloy containing titanium and aluminum for precipitation hardening and molybdenum for solid-solution strengthening . This alloy has high yield strength and excellent creep resistance at temperatures up to approximately 600°C (1110°F)
Specifications & AvailableAlloy 901 is produced using consumable electrode remelting or vacuum induction melting (VIM), often followed by vacuum arc remelting (VAR) or electroslag remelting (ESR) to ensure high purity and metallurgical homogeneity . Available Forms: Round bar, flat bar, rod, forging stock, wire, welding wire Size Limitation: Bars and forgings up to 5 inches (127 mm) diameter; forging stock any size Specifications: AMS5660N, ASTM B409, UNS N09901, Werkstoff Nr. 2.4662, BS HR53
Fabrication Solution Annealing: 1080-1107°C (1975-2025°F), water quench Stabilization: 760-802°C (1400-1475°F) × 2-4 hours, air cool Aging: 704-746°C (1300-1375°F) × 24 hours, air cool Hot Working: Forging requires careful process control to avoid directional properties; proper parameter selection eliminates notch sensitivity Machining: Good machinability in solution-annealed condition; carbide tooling recommended Welding: Good weldability using GTAW (TIG); matching filler metal recommended
Applications Gas Turbine Engine Components: Turbine discs, compressor discs, shaft rings, casings, and seals operating at temperatures up to 650°C (1200°F) Aircraft Engine Parts: Rotating components requiring high yield strength and creep resistance Fasteners: High-strength bolts and studs for elevated temperature service Structural Components: Stationary parts in gas turbines requiring good mechanical properties at intermediate temperatures Industrial Gas Turbines: Similar rotating and stationary components for power generation Ring and Disc Forgings: Available as forged rings and discs for engine construction
