Nickel Alloy Alloy 22-AW vs Alloy 22 Cast
Nickel Alloy · Alloy 22 temper comparison
Alloy 22-AW and Alloy 22 Cast are two conditions of the same nickel alloy grade, Alloy 22: AW (as-welded deposit) versus Cast (as cast). The chemistry is identical, so every difference below comes from the condition. Alloy 22-AW is the stronger of the two: yield strength 480 MPa (69.6 ksi) against 320 MPa (46.4 ksi) for Alloy 22 Cast, about 50% more; tensile strength follows at 760 MPa (110 ksi) vs 620 MPa (89.9 ksi). Alloy 22-AW is the more ductile: elongation 40% versus 28% for Alloy 22 Cast, and Alloy 22-AW is harder (225 HV vs 210 HV).
Alloy 22-AWChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
Alloy 22-AW vs Alloy 22 Cast: 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.

Alloy 22-AW vs Alloy 22 Cast — frequently asked
Is Alloy 22-AW stronger than Alloy 22 Cast?
Yes. Alloy 22-AW has a typical yield strength of 480 MPa (69.6 ksi) against 320 MPa (46.4 ksi) for Alloy 22 Cast — about 50% more. Tensile strength is 760 MPa (110 ksi) vs 620 MPa (89.9 ksi).
Which condition does FabDigit quote by default, AW or Cast?
ANN is the default Alloy 22 condition in the FabDigit quote flow (neither AW nor Cast). 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 welds better, Alloy 22-AW or Alloy 22 Cast?
Alloy 22-AW. Its weldability rates excellent (85/100) against very good (78/100) for Alloy 22 Cast.
