Main Properties

Key Properties

● High-Temperature Oxidation Resistance:

Excels in environments up to 1200°C (2200°F) due to a stable, adherent Al₂O₃ layer, enhanced by yttrium to prevent spalling.

● Mechanical Strength:

Good creep and thermal fatigue resistance, ideal for cyclic thermal environments.

● Corrosion Resistance:

Performs well in oxidizing, nitriding, and carburizing atmospheres.

Fabrication:

● Welding:

Compatible with GTAW (TIG) and resistance welding; post-weld annealing recommended to relieve stresses.

● Formability:

Available in wire form (AMS 5876 standard), typically supplied annealed for ease of processing.

Applications:

● Aerospace:

Combustors, flame holders, turbine seals.

● Industrial:

Gas turbine components, furnace fixtures (radiant tubes, muffles), heat treatment equipment.

Comparisons:

● Outperforms Hastelloy X and Inconel 601 in oxidation resistance due to Al/Y content.

● Less intermediate-temperature strength than alloys like Inconel 718 but superior at ultra-high temperatures.

Considerations:

● Cost: Higher due to specialized alloying elements.

● Thermal Stability: Optimized to avoid detrimental phase formation, ensuring longevity in extreme conditions.

Standards:

● AMS 5876: Certifies aerospace-grade wire for critical applications.

Conclusion:

Haynes 214 wire is a premium choice for extreme high-temperature applications where oxidation resistance and thermal stability are paramount, particularly in aerospace and industrial heating systems. Its unique Al/Y-enhanced alumina scale offers unmatched protection in harsh environments.
