Nickel Alloy MP35N-ANN vs MP35N CW-AGED-285
Nickel Alloy · MP35N temper comparison
MP35N-ANN and MP35N CW-AGED-285 are two conditions of the same nickel alloy grade, MP35N: ANN (annealed) versus CW-AGED-285 (cold Worked + Aged, 285 ksi class). The chemistry is identical, so every difference below comes from the condition. MP35N CW-AGED-285 is the stronger of the two: yield strength 1,930 MPa (280 ksi) against 415 MPa (60.2 ksi) for MP35N-ANN, about 4.7 times as much; tensile strength follows at 2,030 MPa (294 ksi) vs 950 MPa (138 ksi). In exchange, MP35N-ANN is the more ductile: elongation 65% versus 8% for MP35N CW-AGED-285, and MP35N CW-AGED-285 is harder (540 HB vs 210 HB). On the shop floor, MP35N-ANN machines more easily (poor vs not recommended) and MP35N-ANN welds better (good vs poor).

MP35N-ANN vs MP35N CW-AGED-285: 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 CW-AGED-285 — frequently asked
Is MP35N CW-AGED-285 stronger than MP35N-ANN?
Yes. MP35N CW-AGED-285 has a typical yield strength of 1,930 MPa (280 ksi) against 415 MPa (60.2 ksi) for MP35N-ANN — about 4.7 times as much. Tensile strength is 2,030 MPa (294 ksi) vs 950 MPa (138 ksi).
Which condition does FabDigit quote by default, ANN or CW-AGED-285?
CW-AGED-260 is the default MP35N condition in the FabDigit quote flow (neither ANN nor CW-AGED-285). 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 CW-AGED-285?
MP35N-ANN. Its machinability rates poor (20/100) against not recommended (10/100) for MP35N CW-AGED-285; for welding the order is MP35N-ANN first (good, 55/100) then MP35N CW-AGED-285 (poor, 20/100).
