Nickel Alloy Grade Data Sheet

HAYNES 214

HAYNES 214 is a nickel-chromium-aluminum-iron wrought alloy developed for exceptional oxidation resistance in high-temperature, relatively low-stress service. At approximately 955 °C and above, its aluminum content promotes a tightly adherent alumina-rich protective scale that resists oxidation, carburization, nitriding and selected chlorine-bearing oxidizing environments. Typical applications include furnace mesh belts, trays, fixtures, refractory anchors, flame hoods, rotary calciner components, ceramic-firing equipment, gas-turbine honeycomb seals, combustor splash plates, catalytic-converter internals and high-temperature incinerator components.

Material Selection Guide

When to consider HAYNES 214

This guide helps buyers connect service conditions with the typical advantage of Alloy 625. Final selection should consider medium concentration, temperature, pressure, fabrication, availability and budget.

Service Requirement Recommended Alloy Reason for Selection Buyer Note
Maximum oxidation resistance above 955 °C HAYNES 214 Forms a tightly adherent alumina-rich scale with exceptional resistance to oxidation and exfoliation. Confirm that mechanical loads remain within the alloy’s high-temperature strength limits.
Very high-temperature, relatively low-stress furnace component HAYNES 214 Useful oxidation resistance can extend to approximately 1260 °C during long exposure. Temperature capability depends on atmosphere, thermal cycling and section thickness.
High-temperature structural load and creep strength HAYNES 230 or HAYNES 188 These alloys generally provide a stronger balance of creep strength and oxidation resistance. Use time-temperature-stress data for final selection.
Oxidizing chlorine-contaminated environment HAYNES 214 The alumina-rich scale can provide strong resistance in selected high-temperature oxidizing chlorine service. Confirm chlorine content, oxygen potential, deposits and temperature.
Moderate-temperature oxidation service Alloy 601 or HAYNES 230 These grades may be more practical where the full alumina-forming advantage of HAYNES 214 is not developed. Compare strength, fabrication, availability and total operating cost.
Aqueous chemical corrosion service Select a corrosion-resistant nickel alloy HAYNES 214 is optimized for high-temperature gaseous environments rather than broad aqueous corrosion resistance. Provide the complete chemical composition, concentration and temperature.

FAQ

HAYNES 214 questions from buyers

Find practical answers about procurement, standards, fabrication and industrial applications.

HAYNES 214 is used for furnace mesh belts, trays, fixtures, refractory anchors, flame hoods, rotary calciners, ceramic-firing equipment, gas-turbine honeycomb seals, combustor splash plates, catalytic-converter internals and high-temperature incinerator components.

Yes. UNS N07214 is the standardized UNS designation for HAYNES 214, a nickel-chromium-aluminum-iron high-temperature oxidation-resistant alloy.

The alloy can provide long-term oxidation resistance in air or combustion gases up to approximately 1260 °C and useful short-term resistance near 1315 °C. These values describe environmental resistance, not allowable load-bearing temperature.

At approximately 955 °C and above, its aluminum content promotes a thin, tightly adherent Al2O3-rich protective scale. This scale grows slowly and resists spalling during prolonged high-temperature exposure.

YSN128 can quote sheet, plate, strip, foil, bar, rod, wire and matching welding wire. Drawing-based tubes, fasteners, fittings, flanges and forgings can be reviewed for custom production.

No generic ASTM or AMS base-material specification is currently listed by Haynes International for UNS N07214. Base products should be ordered to an agreed producer or customer specification, while structural matching filler wire is available to HAYNES PS-6076-2.

Yes. It can be welded by GTAW, GMAW, SMAW and plasma-arc processes. Heat input and restraint must be minimized, interpass temperature should remain low, and qualified procedures should address its susceptibility to strain-age cracking.

Please send the UNS or alloy grade, product form, dimensions, quantity, operating temperature, atmosphere, design load, thermal-cycle details, delivery condition, inspection requirements, certificate type and destination. Drawings and welding requirements should be supplied for finished components.
