Working with Haynes 214-CW
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.
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-CW — frequently asked
What is Haynes 214-CW used for?
Haynes 214-CW 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-CW?
Haynes 214-CW has a typical yield strength of 950 MPa (138 ksi) and a tensile strength of 1,150 MPa (167 ksi) — stronger than 95% of nickel alloy grades. Strength varies by condition: see the 3 listed tempers.
Is Haynes 214-CW easy to machine?
Not especially — machinability is rated poor (15/100, worse than 76% 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-CW be welded?
With care — weldability is rated fair (50/100). 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-CW?
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-CW 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-CW?
Haynes 214-CW is rated for continuous use to about 900°C (1,652 °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.
