Nickel Alloy Haynes 230-AC vs Haynes 230-AW
Nickel Alloy · Haynes 230 temper comparison
Haynes 230-AC and Haynes 230-AW are two conditions of the same nickel alloy grade, Haynes 230: AC (spheroidize annealed) versus AW (as-welded deposit). The chemistry is identical, so every difference below comes from the condition. Haynes 230-AW is the stronger of the two: yield strength 460 MPa (66.7 ksi) against 345 MPa (50 ksi) for Haynes 230-AC, about 33% more; tensile strength follows at 810 MPa (117 ksi) vs 620 MPa (89.9 ksi). Haynes 230-AW is the more ductile: elongation 30% versus 12% for Haynes 230-AC, and Haynes 230-AW is harder (225 HV vs 205 HV). On the shop floor, Haynes 230-AW welds better (very good vs good).

Haynes 230-AC vs Haynes 230-AW: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all nickel alloy grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.

Haynes 230-AC vs Haynes 230-AW — frequently asked
Is Haynes 230-AW stronger than Haynes 230-AC?
Yes. Haynes 230-AW has a typical yield strength of 460 MPa (66.7 ksi) against 345 MPa (50 ksi) for Haynes 230-AC — about 33% more. Tensile strength is 810 MPa (117 ksi) vs 620 MPa (89.9 ksi).
Which condition does FabDigit quote by default, AC or AW?
SA is the default Haynes 230 condition in the FabDigit quote flow (neither AC nor AW). The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.
Which welds better, Haynes 230-AC or Haynes 230-AW?
Haynes 230-AW. Its weldability rates very good (75/100) against good (65/100) for Haynes 230-AC.
