Nickel 205-ANN vs Nickel 205-HR
Nickel Alloy · Nickel 205 temper comparison
Nickel 205-ANN and Nickel 205-HR are two conditions of the same nickel alloy grade, Nickel 205: ANN (annealed) versus HR (hot rolled). The chemistry is identical, so every difference below comes from the condition. Nickel 205-HR is the stronger of the two: yield strength 200 MPa (29 ksi) against 145 MPa (21 ksi) for Nickel 205-ANN, about 38% more; tensile strength follows at 500 MPa (72.5 ksi) vs 440 MPa (63.8 ksi). In exchange, Nickel 205-ANN is the more ductile: elongation 45% versus 40% for Nickel 205-HR, and Nickel 205-HR is harder (110 HB vs 95 HB).
Nickel 205-ANNChoose it when the part is bent, formed or impact-loaded.
Nickel 205-HRChoose it when strength drives the design.
Nickel 205-ANN vs Nickel 205-HR: 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.
