Nickel Alloy 601GC-AW vs 601GC-CD
Nickel Alloy · 601GC temper comparison
601GC-AW and 601GC-CD are two conditions of the same nickel alloy grade, 601GC: AW (as-welded deposit) versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. 601GC-CD is the stronger of the two: yield strength 550 MPa (79.8 ksi) against 370 MPa (53.7 ksi) for 601GC-AW, about 49% more; tensile strength follows at 830 MPa (120 ksi) vs 640 MPa (92.8 ksi). In exchange, 601GC-AW is the more ductile: elongation 33% versus 25% for 601GC-CD, and 601GC-CD is harder (230 HB vs 185 HB). 601GC-AW runs hotter in service (1,150°C vs 600°C continuous).
601GC-AWChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
601GC-CDChoose it when strength drives the design.
601GC-AW vs 601GC-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.

601GC-AW vs 601GC-CD — frequently asked
Is 601GC-CD stronger than 601GC-AW?
Yes. 601GC-CD has a typical yield strength of 550 MPa (79.8 ksi) against 370 MPa (53.7 ksi) for 601GC-AW — about 49% more. Tensile strength is 830 MPa (120 ksi) vs 640 MPa (92.8 ksi).
Which condition does FabDigit quote by default, AW or CD?
ANN is the default 601GC condition in the FabDigit quote flow (neither AW nor CD). 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, 601GC-AW or 601GC-CD?
601GC-CD, by a small margin. Both rate poor for machinability — 26/100 against 20/100 for 601GC-AW; for welding the order is 601GC-CD first (excellent, 85/100) then 601GC-AW (very good, 80/100).
