Overview


Haynes Alloys Flat Wire Haynes 214 ,Identical to other Haynes 214 forms.



Limiting Chemical Composition, %


Nickel...........................................................................................................................................75.0-80.0

Chromium............................................................................................................................................16.0

Aluminum..............................................................................................................................................4.5

Iron.........................................................................................................................................................3.0

Yttrium (Y): Trace (enhances oxide adhesion).



Key Properties


● High-Temperature Performance:

Retains oxidation resistance up to 1200°C (2200°F); yttrium-stabilized Al₂O₃ layer prevents spalling.

Suitable for cyclic thermal environments due to thermal fatigue resistance.


● Mechanical Strength:

Higher tensile strength than round wire (cold-rolled processing increases work hardening).

Retains creep resistance under prolonged stress.


● Corrosion Resistance:

Resists oxidizing, carburizing, and nitriding atmospheres.



Fabrication & Processing


● Production:

Manufactured via cold rolling or precision rolling of round wire to achieve flat profiles.


● Formability:

Annealed condition (AMS 5876) improves bendability for complex shapes.

Avoid excessive bending radii to prevent edge cracking.


● Machining:

Challenging due to work hardening; use carbide tools and low-speed techniques.

Coolants recommended to manage heat during cutting.


● Welding:

Compatible with TIG (GTAW) and laser welding; post-weld annealing reduces residual stresses.



Applications:


● Aerospace:

High-temperature seals, gaskets, and shims in combustion chambers.

Sensor leads or resistive heating elements in extreme environments.


● Industrial:

Furnace components (e.g., radiant heater strips, thermocouple sheaths).

Electrical contacts in high-temperature industrial sensors.


● Energy:

Fuel cell interconnects or heat exchanger strips in gas turbines.



Standards & Specifications


● AMS 5876: Aerospace standard for annealed Haynes 214 wire (applicable to flat wire processing).

● Custom Dimensions: Typically available in thicknesses from 0.1–3 mm and widths up to 25 mm (varies by supplier).



Considerations


● vs. Round Wire:

Flat wire offers greater surface-area-to-volume ratio for improved heat dissipation or electrical contact.

Slightly lower ductility due to cold working.


● vs. Competing Alloys (Inconel 600, Hastelloy X):

Superior oxidation resistance above 1000°C due to Al/Y-enhanced oxide layer.

Less ductile than Inconel 600 at room temperature.



Key Considerations


● Surface Finish:

Post-rolling pickling or electropolishing may be needed to remove oxides.

● Anisotropy:

Mechanical properties may vary slightly along vs. across the rolling direction.

● Cost:

Higher than conventional nickel alloys due to specialized processing and yttrium content.

● Thermal Stability:

Avoid prolonged exposure to 650–870°C (risk of embrittlement from sigma phase formation).


Conclusion:


Haynes 214 flat wire is engineered for high-temperature applications requiring a thin, flat profile with uncompromised oxidation resistance. Its niche lies in aerospace seals, industrial heating systems, and precision components where geometry and extreme-environment performance are critical. While challenging to machine, its ability to withstand temperatures up to 1200°C makes it indispensable in mission-critical scenarios.
