Nickel Alloy M35-2-AC vs M35-2-ANN
Nickel Alloy · M35-2 temper comparison
M35-2-AC and M35-2-ANN are two conditions of the same nickel alloy grade, M35-2: AC (spheroidize annealed) versus ANN (annealed). The chemistry is identical, so every difference below comes from the condition. M35-2-AC is the stronger of the two: yield strength 235 MPa (34.1 ksi) against 210 MPa (30.5 ksi) for M35-2-ANN, about 12% more. In exchange, M35-2-ANN is the more ductile: elongation 37% versus 32% for M35-2-AC, and M35-2-AC is harder (130 HB vs 118 HB).
M35-2-ACChoose it when strength drives the design.
M35-2-ANNChoose it when the part is bent, formed or impact-loaded.
M35-2-AC vs M35-2-ANN: 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.

M35-2-AC vs M35-2-ANN — frequently asked
Is M35-2-AC stronger than M35-2-ANN?
Yes. M35-2-AC has a typical yield strength of 235 MPa (34.1 ksi) against 210 MPa (30.5 ksi) for M35-2-ANN — about 12% more. Tensile strength is 490 MPa (71.1 ksi) vs 470 MPa (68.2 ksi).
Which condition does FabDigit quote by default, AC or ANN?
AC is the default M35-2 condition in the FabDigit quote flow. 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, M35-2-AC or M35-2-ANN?
M35-2-ANN. Its weldability rates very good (75/100) against very good (70/100) for M35-2-AC.
