Nickel Alloy ENiCrFe-2-ANN vs ENiCrFe-2-AW
Nickel Alloy · ENiCrFe-2 temper comparison
ENiCrFe-2-ANN and ENiCrFe-2-AW are two conditions of the same nickel alloy grade, ENiCrFe-2: ANN (annealed) versus AW (as-welded deposit). The chemistry is identical, so every difference below comes from the condition. ENiCrFe-2-AW is the stronger of the two: yield strength 420 MPa (60.9 ksi) against 300 MPa (43.5 ksi) for ENiCrFe-2-ANN, about 40% more; tensile strength follows at 620 MPa (89.9 ksi) vs 570 MPa (82.7 ksi). In exchange, ENiCrFe-2-ANN is the more ductile: elongation 45% versus 38% for ENiCrFe-2-AW, and ENiCrFe-2-AW is harder (195 HB vs 155 HB).

ENiCrFe-2-ANN vs ENiCrFe-2-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.

ENiCrFe-2-ANN vs ENiCrFe-2-AW — frequently asked
Is ENiCrFe-2-AW stronger than ENiCrFe-2-ANN?
Yes. ENiCrFe-2-AW has a typical yield strength of 420 MPa (60.9 ksi) against 300 MPa (43.5 ksi) for ENiCrFe-2-ANN — about 40% more. Tensile strength is 620 MPa (89.9 ksi) vs 570 MPa (82.7 ksi).
Which condition does FabDigit quote by default, ANN or AW?
AW is the default ENiCrFe-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 is easier to machine, ENiCrFe-2-ANN or ENiCrFe-2-AW?
ENiCrFe-2-ANN, by a small margin. Both rate poor for machinability — 34/100 against 28/100 for ENiCrFe-2-AW.
