What is Haynes 214?
Haynes 214 is a Ni-Cr-Al-Fe alloy (N07214) that forms a protective alumina rather than chromia scale, giving oxidation resistance to about 1400 °C against a listed maximum service temperature of 1200 °C. It is used for thin-section furnace and combustion hardware and is available as foil, sheet, plate and bar in solution-annealed, cold-worked and as-welded conditions; annealed values are 565 MPa yield, 915 MPa tensile, 38% elongation and 92 HRB. Machinability is low (20) while weldability (60) and formability (65) remain workable. Alloy 800H is the lower-cost choice where service stays near 815 °C. Haynes 214 has a density of 8.05 g/cm³ (0.291 lb/in³), lighter than 83% of nickel alloy grades. It melts at 1,338°C (2,440 °F). Haynes 214 has a yield strength of 565 MPa (81.9 ksi) and a tensile strength of 915 MPa (133 ksi) — stronger than 81% of nickel alloy grades. Elongation at break is 38% and the elastic modulus is 218 GPa (31.6 Msi).

Working with Haynes 214
Is Haynes 214 easy to machine?
Machine like a tough Ni superalloy: rigid setups, positive-rake carbide, low speed/heavy feed, flood coolant, avoid dwelling to prevent work hardening.
Can Haynes 214 be welded?
GTAW/GMAW/resistance welding with matching 214 filler; keep interpass heat and restraint low, clean off alumina scale between passes, no PWHT normally required.
Can Haynes 214 be formed, bent or molded?
Good cold formability in the annealed condition for sheet and foil; springback is high, so allow for it and re-anneal (~1120–1175 °C, rapid cool) between severe operations.
Haynes 214 chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.

What surface finishes work on Haynes 214?
Not anodizable; grind/pickle or grit-blast plus acid clean to remove oxide before brazing or coating, and pre-oxidize in air to establish the protective alumina layer for service.

Haynes 214 — frequently asked
What is Haynes 214 used for?
Haynes 214 is typically used for furnace hardware, radiant tubes, thermocouple protection tubes and combustor cans. In short: alumina-forming oxidation resistance; weldable to 1200 °C service; available as thin foil.
What is the yield strength of Haynes 214?
Haynes 214 has a typical yield strength of 565 MPa (81.9 ksi) and a tensile strength of 915 MPa (133 ksi) — stronger than 81% of nickel alloy grades. Strength varies by condition: see the 3 listed tempers.
Is Haynes 214 easy to machine?
Not especially — machinability is rated poor (20/100, better than 53% of nickel alloy grades). Machine like a tough Ni superalloy: rigid setups, positive-rake carbide, low speed/heavy feed, flood coolant, avoid dwelling to prevent work hardening.
Can Haynes 214 be welded?
Yes — weldability is rated good (60/100). GTAW/GMAW/resistance welding with matching 214 filler; keep interpass heat and restraint low, clean off alumina scale between passes, no PWHT normally required.
What surface finishes work on Haynes 214?
Not anodizable; grind/pickle or grit-blast plus acid clean to remove oxide before brazing or coating, and pre-oxidize in air to establish the protective alumina layer for service.
Can Haynes 214 be formed, bent or molded?
Good cold formability in the annealed condition for sheet and foil; springback is high, so allow for it and re-anneal (~1120–1175 °C, rapid cool) between severe operations.
What is the maximum service temperature of Haynes 214?
Haynes 214 is rated for continuous use to about 1,200°C (2,192 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between Haynes 214-SA and Haynes 214-CW?
SA is the default condition — standard stocked condition for sheet, strip and foil used in furnace hardware, honeycomb seals and combustor liners. CW: pick for wire, mesh and honeycomb foil where higher room-temperature strength and springiness are needed before service exposure. Yield strength is 565 MPa in SA versus 950 MPa in CW.
