ZYTC Alloy is an ISO 9001 and AS 9120B certified superalloy manufacturer and supplier, offering AMS 5892C Alloy 909 sheet at factory-direct prices with full material traceability and fast global delivery. AMS5892C specification covers a low expansion iron alloy (Incoloy 909 / UNS N19909) in the form of sheet or strip up to 0.250 inch (6.35 mm) in nominal thickness. Alloy 909 is a nickel-iron-cobalt alloy that combines impressive high strength with a constant, low coefficient of thermal expansion. Due to these characteristics, it has wide applications where low expansion together with high strength is required.

Specifications – Alloy 909 Sheet| Specification | Description |
|---|
| AMS 5892C | Sheet and strip – solution heat treated, precipitation hardenable | | UNS N19909 | Unified numbering system | | Incoloy® 909 | Trade name (Special Metals) | | ASTM F1684 | Standard specification for alloy 909 |
Fabrication Solution Annealing: 982°C (1800°F), air cool Aging: 718°C (1325°F) × 8 hours, furnace cool to 621°C (1150°F), hold 8 hours, air cool Forming: Good formability in solution-annealed condition for stamping and shaping Machining: More difficult than standard stainless steels; requires rigid setups, sharp tools, and adequate lubrication Welding: Good weldability using GTAW (TIG); post-weld heat treatment required to restore properties; matching filler metal recommended
ApplicationsGas Turbines: Seals, casings, rings, shrouds, and static structural components requiring tight clearances Rocket Engines: Thrust chambers and structural components for aerospace propulsion Steam Turbine Bolting: High-temperature bolts requiring good stress-rupture properties and corrosion resistance Springs: High-strength springs for elevated temperature service Instrumentation: Gauge blocks, precision measuring devices, and inspection tools requiring dimensional stability Ordnance Hardware: Military components needing stability across temperature ranges Glass Sealing Applications: Hermetic seals where expansion matching is required
