Nickel Alloy Alloy 120-ANN vs Alloy 120 HR-ANN
Nickel Alloy · Alloy 120 temper comparison
Alloy 120-ANN and Alloy 120 HR-ANN are two conditions of the same nickel alloy grade, Alloy 120: ANN (annealed) versus HR-ANN (hot Rolled + Annealed). The chemistry is identical, so every difference below comes from the condition. Alloy 120-ANN is the stronger of the two: yield strength 331 MPa (48 ksi) against 310 MPa (45 ksi) for Alloy 120 HR-ANN, about 7% more; tensile strength follows at 758 MPa (110 ksi) vs 720 MPa (104 ksi).

Alloy 120-ANN vs Alloy 120 HR-ANN: 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.
