Nickel Alloy N12MV-AC vs N12MV-AW
Nickel Alloy · N12MV temper comparison
N12MV-AC and N12MV-AW are two conditions of the same nickel alloy grade, N12MV: AC (spheroidize annealed) versus AW (as-welded deposit). The chemistry is identical, so every difference below comes from the condition. N12MV-AW is the stronger of the two: tensile strength 550 MPa (79.8 ksi) against 520 MPa (75.4 ksi) for N12MV-AC, about 6% more. N12MV-AW is the more ductile: elongation 7% versus 5% for N12MV-AC, and N12MV-AC is harder (232 HV vs 220 HV). N12MV-AC runs hotter in service (540°C vs 480°C continuous).
N12MV-ACChoose it when the part sees heat.
N12MV-AWChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
N12MV-AC vs N12MV-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.

N12MV-AC vs N12MV-AW — frequently asked
Is N12MV-AW stronger than N12MV-AC?
Yes. N12MV-AW has a typical tensile strength of 550 MPa (79.8 ksi) against 520 MPa (75.4 ksi) for N12MV-AC — about 6% more.
Which condition does FabDigit quote by default, AC or AW?
SA is the default N12MV 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.
When should I choose N12MV-AC over N12MV-AW?
Pick N12MV-AC when the part sees heat. Pick N12MV-AW when strength drives the design, or when the part is bent, formed or impact-loaded.
