Nickel Alloy Alloy 22-ANN vs Alloy 22-CD
Nickel Alloy · Alloy 22 temper comparison
Alloy 22-ANN and Alloy 22-CD are two conditions of the same nickel alloy grade, Alloy 22: ANN (annealed) versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. Alloy 22-CD is the stronger of the two: yield strength 800 MPa (116 ksi) against 400 MPa (58 ksi) for Alloy 22-ANN, about 100% more; tensile strength follows at 1,000 MPa (145 ksi) vs 800 MPa (116 ksi). In exchange, Alloy 22-ANN is the more ductile: elongation 62% versus 25% for Alloy 22-CD, and Alloy 22-CD is harder (310 HV vs 210 HV).
Alloy 22-ANNChoose it when the part is bent, formed or impact-loaded.
Alloy 22-CDChoose it when strength drives the design.
Alloy 22-ANN vs Alloy 22-CD: 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-ANN vs Alloy 22-CD — frequently asked
Is Alloy 22-CD stronger than Alloy 22-ANN?
Yes. Alloy 22-CD has a typical yield strength of 800 MPa (116 ksi) against 400 MPa (58 ksi) for Alloy 22-ANN — about 100% more. Tensile strength is 1,000 MPa (145 ksi) vs 800 MPa (116 ksi).
Which condition does FabDigit quote by default, ANN or CD?
ANN is the default Alloy 22 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, Alloy 22-ANN or Alloy 22-CD?
Alloy 22-CD, by a small margin. Both rate poor for machinability — 20/100 against 15/100 for Alloy 22-ANN.
