Nickel 201-ANN vs Nickel 201-H34
Nickel Alloy · Nickel 201 temper comparison
Nickel 201-ANN and Nickel 201-H34 are two conditions of the same nickel alloy grade, Nickel 201: ANN (annealed) versus H34 (strain hardened and stabilized, half hard). The chemistry is identical, so every difference below comes from the condition. Nickel 201-H34 is the stronger of the two: yield strength 460 MPa (66.7 ksi) against 105 MPa (15.2 ksi) for Nickel 201-ANN, about 4.4 times as much; tensile strength follows at 560 MPa (81.2 ksi) vs 415 MPa (60.2 ksi). In exchange, Nickel 201-ANN is the more ductile: elongation 47% versus 8% for Nickel 201-H34, and Nickel 201-H34 is harder (185 HB vs 90 HB). Nickel 201-ANN runs hotter in service (650°C vs 315°C continuous). On the shop floor, Nickel 201-H34 machines more easily (fair vs poor) and Nickel 201-ANN welds better (excellent vs very good).
Nickel 201-ANNChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
Nickel 201-H34Choose it when strength drives the design, or when the part is machined in volume.
Nickel 201-ANN vs Nickel 201-H34: 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.
