Compare all 8 conditionsHide
| Condition · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness | Conductivity |
|---|---|---|---|---|---|---|
Spheroidize annealed | Cast burner nozzles, grid and fixture parts where a complex shape beats wrought fabrication; coarse dendritic structure gives lower ductility than wrought. | 345 | 620 | 12 | 210 HB | — |
Cast + HIP + solution annealed | Preferred cast condition for pressure-containing or cyclic-load parts: HIP closes microporosity and the solution anneal homogenizes carbides. | 350 | 700 | 22 | 14 HRC | 1.4 % IACS |
As cast | Investment- or sand-cast N06230 with coarse dendritic structure; lower ductility and strength than wrought product but retains the alloy's oxidation and creep resistance. | 355 | 660 | 20 | 205 HB | 9 W/m·K |
SADefault Solution annealed sheet/plate | Standard stocked condition for sheet, strip and plate — best balance of strength, ductility and high-temperature stability. | 390 | 870 | 48 | 195 HB | — |
Wrought (mill-annealed sheet, plate, bar, tube) | Standard wrought Ni-22Cr-14W-2Mo-La solution-annealed mill product with balanced high-temperature strength, oxidation resistance to ~1150 °C and good fabricability. | 390 | 860 | 48 | 200 HB | 1.4 % IACS |
Cold drawn + solution annealed tube, pipe and small bar | Seamless tubing and precision bar with bright annealed finish for furnace/heat-exchanger service. | 395 | 860 | 46 | 17 HRC | 1.4 % IACS |
As-welded deposit | Property set for all-weld-metal joints made with matching 230-W wire; no post-weld heat treatment normally required. | 460 | 810 | 30 | 18 HRC | 1.4 % IACS |
Cold worked | Use where high room-temperature strength or spring action is needed; ductility and long-term high-T stability are reduced (recrystallizes above ~900 °C). | 1,000 | 1,200 | 6 | 35 HRC | 1.4 % IACS |

What is Haynes 230?
Haynes 230 (N06230, 2.4733, NiCr22W14Mo) is a Ni-22Cr-14W-2Mo superalloy strengthened mainly in solid solution by tungsten and molybdenum, available as wrought sheet, plate, bar, tube and as castings including HIP-consolidated parts. Engineers select it for high-temperature strength, oxidation resistance and fabricability to 1150 °C, with 390 MPa yield, 870 MPa tensile, 48% elongation, 195 HB (95 HRB), weldability score 80 and formability score 70. Machinability is low (score 18) and material cost is high; Alloy 617 or 601 is the alternative when 230-level creep strength is not required. Haynes 230 has a density of 8.97 g/cm³ (0.324 lb/in³), heavier than 93% of nickel alloy grades. It melts at 1,301°C (2,374 °F).

Working with Haynes 230
Is Haynes 230 easy to machine?
Machine like a work-hardening Ni-base superalloy: rigid setups, positive-rake sharp carbide or ceramic tooling, low speed / heavy positive feed, flood coolant, and never dwell or rub.
Can Haynes 230 be welded?
Readily joined by GTAW/GMAW/PAW/RSW with matching 230-W filler; keep interpass temperature low and heat input moderate, no PWHT needed for most wrought sections.
Can Haynes 230 be formed, bent or molded?
Good cold formability in the annealed condition but forming loads are ~50 % above austenitic stainless; hot work 950–1200 °C and re-solution anneal at 1177–1246 °C with rapid cool after heavy cold work.

What surface finishes work on Haynes 230?
Pickle/grit-blast to remove oxide before service or coating; not anodizable — aluminide or MCrAlY diffusion coatings are used for extreme oxidation/hot-corrosion duty, and the alloy polishes to a bright finish.
Surface treatments FabDigit runs on nickel alloy parts — pick them in the quote configurator or call them out on the drawing. Each links to its datasheet in the surface-finish library (thickness, specs, call-out, material verdicts).

Haynes 230 — frequently asked
What is Haynes 230 used for?
Haynes 230 is typically used for gas turbine combustor liners, industrial furnace hardware, chemical processing components and aerospace afterburners. In short: strongest solid-solution Ni-Cr grade; fabricable to 1150 °C; combustor-liner standard.
What is the yield strength of Haynes 230?
Haynes 230 has a typical yield strength of 390 MPa (56.6 ksi) and a tensile strength of 870 MPa (126 ksi) — stronger than 51% of nickel alloy grades. Strength varies by condition: see the 8 listed tempers.
Is Haynes 230 easy to machine?
Not especially — machinability is rated poor (18/100, worse than 61% of nickel alloy grades). Machine like a work-hardening Ni-base superalloy: rigid setups, positive-rake sharp carbide or ceramic tooling, low speed / heavy positive feed, flood coolant, and never dwell or rub.
Can Haynes 230 be welded?
Yes — weldability is rated very good (80/100). Readily joined by GTAW/GMAW/PAW/RSW with matching 230-W filler; keep interpass temperature low and heat input moderate, no PWHT needed for most wrought sections.
What surface finishes work on Haynes 230?

Can Haynes 230 be formed, bent or molded?
Good cold formability in the annealed condition but forming loads are ~50 % above austenitic stainless; hot work 950–1200 °C and re-solution anneal at 1177–1246 °C with rapid cool after heavy cold work.
What is the maximum service temperature of Haynes 230?
Haynes 230 is rated for continuous use to about 1,150°C (2,102 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between Haynes 230-SA and Haynes 230-CW?
SA is the default condition — standard stocked condition for sheet, strip and plate — best balance of strength, ductility and high-temperature stability. CW: use where high room-temperature strength or spring action is needed; ductility and long-term high-T stability are reduced (recrystallizes above ~900 °C). Yield strength is 390 MPa in SA versus 1,000 MPa in CW.
