Nickel Alloy ENiCrFe-2-ANN vs ENiCrFe-2 AW+SR
Nickel Alloy · ENiCrFe-2 temper comparison
ENiCrFe-2-ANN and ENiCrFe-2 AW+SR are two conditions of the same nickel alloy grade, ENiCrFe-2: ANN (annealed) versus AW+SR (as Welded + PWHT / stress relief). The chemistry is identical, so every difference below comes from the condition. ENiCrFe-2 AW+SR is the stronger of the two: yield strength 380 MPa (55.1 ksi) against 300 MPa (43.5 ksi) for ENiCrFe-2-ANN, about 27% more. In exchange, ENiCrFe-2-ANN is the more ductile: elongation 45% versus 40% for ENiCrFe-2 AW+SR, and ENiCrFe-2 AW+SR is harder (185 HB vs 155 HB).
ENiCrFe-2-ANNChoose it when the part is bent, formed or impact-loaded.
ENiCrFe-2 AW+SRChoose it when strength drives the design.
ENiCrFe-2-ANN vs ENiCrFe-2 AW+SR: 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+SR — frequently asked
Is ENiCrFe-2 AW+SR stronger than ENiCrFe-2-ANN?
Yes. ENiCrFe-2 AW+SR has a typical yield strength of 380 MPa (55.1 ksi) against 300 MPa (43.5 ksi) for ENiCrFe-2-ANN — about 27% more. Tensile strength is 590 MPa (85.6 ksi) vs 570 MPa (82.7 ksi).
Which condition does FabDigit quote by default, ANN or AW+SR?
AW is the default ENiCrFe-2 condition in the FabDigit quote flow (neither ANN nor AW+SR). 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 ENiCrFe-2-ANN over ENiCrFe-2 AW+SR?
Pick ENiCrFe-2-ANN when the part is bent, formed or impact-loaded. Pick ENiCrFe-2 AW+SR when strength drives the design.
