Nickel Alloy 601GC-ANN vs 601GC-AW
Nickel Alloy · 601GC temper comparison
601GC-ANN and 601GC-AW are two conditions of the same nickel alloy grade, 601GC: ANN (annealed) versus AW (as-welded deposit). The chemistry is identical, so every difference below comes from the condition. 601GC-AW is the stronger of the two: yield strength 370 MPa (53.7 ksi) against 310 MPa (45 ksi) for 601GC-ANN, about 19% more. In exchange, 601GC-ANN is the more ductile: elongation 48% versus 33% for 601GC-AW, and 601GC-AW is harder (185 HB vs 170 HB).

601GC-ANN vs 601GC-AW: 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.
