Nickel Alloy 800-ANN vs 800-AW
Nickel Alloy · 800 temper comparison
800-ANN and 800-AW are two conditions of the same nickel alloy grade, 800: ANN (annealed) versus AW (as-welded deposit). The chemistry is identical, so every difference below comes from the condition. 800-AW is the stronger of the two: yield strength 320 MPa (46.4 ksi) against 250 MPa (36.3 ksi) for 800-ANN, about 28% more. In exchange, 800-ANN is the more ductile: elongation 45% versus 35% for 800-AW, and 800-AW is harder (160 HB vs 138 HB).
800-ANNChoose it when the part is bent, formed or impact-loaded.
800-AWChoose it when strength drives the design.
800-ANN vs 800-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.

800-ANN vs 800-AW — frequently asked
Is 800-AW stronger than 800-ANN?
Yes. 800-AW has a typical yield strength of 320 MPa (46.4 ksi) against 250 MPa (36.3 ksi) for 800-ANN — about 28% more. Tensile strength is 600 MPa (87 ksi) vs 600 MPa (87 ksi).
Which condition does FabDigit quote by default, ANN or AW?
ANN is the default 800 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, 800-ANN or 800-AW?
800-ANN, by a small margin. Both rate poor for machinability — 30/100 against 25/100 for 800-AW.
