Haynes Alloys Wire Haynes 214
Overview
Haynes Alloys Wire Haynes 214 is a nickel-chromium-aluminum-iron alloy enhanced with yttrium. Typical.
Limiting Chemical Composition, %
Nickel...........................................................................................................................................75.0-80.0
Chromium............................................................................................................................................16.0
Aluminum..............................................................................................................................................4.5
Iron.........................................................................................................................................................3.0
Yttrium (Y): Trace amounts (improves oxide layer adhesion)
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.
