Nickel Alloy MP35N-ANN vs MP35N HW-AGED
Nickel Alloy · MP35N temper comparison
MP35N-ANN and MP35N HW-AGED are two conditions of the same nickel alloy grade, MP35N: ANN (annealed) versus HW-AGED (hot Worked + Aged). The chemistry is identical, so every difference below comes from the condition. MP35N HW-AGED is the stronger of the two: yield strength 830 MPa (120 ksi) against 415 MPa (60.2 ksi) for MP35N-ANN, about 100% more; tensile strength follows at 1,240 MPa (180 ksi) vs 950 MPa (138 ksi). In exchange, MP35N-ANN is the more ductile: elongation 65% versus 25% for MP35N HW-AGED, and MP35N HW-AGED is harder (340 HB vs 210 HB). On the shop floor, MP35N-ANN welds better (good vs fair).
MP35N-ANNChoose it when the part is bent, formed or impact-loaded, or when it will be welded.
MP35N HW-AGEDChoose it when strength drives the design.
MP35N-ANN vs MP35N HW-AGED: 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.

MP35N-ANN vs MP35N HW-AGED — frequently asked
Is MP35N HW-AGED stronger than MP35N-ANN?
Yes. MP35N HW-AGED has a typical yield strength of 830 MPa (120 ksi) against 415 MPa (60.2 ksi) for MP35N-ANN — about 100% more. Tensile strength is 1,240 MPa (180 ksi) vs 950 MPa (138 ksi).
Which condition does FabDigit quote by default, ANN or HW-AGED?
CW-AGED-260 is the default MP35N condition in the FabDigit quote flow (neither ANN nor HW-AGED). 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 is easier to machine, MP35N-ANN or MP35N HW-AGED?
MP35N-ANN, by a small margin. Both rate poor for machinability — 20/100 against 15/100 for MP35N HW-AGED; for welding the order is MP35N-ANN first (good, 55/100) then MP35N HW-AGED (fair, 35/100).
