Nickel Alloy 601GC-CD vs 601GC SA-CG
Nickel Alloy · 601GC temper comparison
601GC-CD and 601GC SA-CG are two conditions of the same nickel alloy grade, 601GC: CD (cold drawn) versus SA-CG (high-temperature (coarse-grain) solution anneal). 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 270 MPa (39.2 ksi) for 601GC SA-CG, about 104% more; tensile strength follows at 830 MPa (120 ksi) vs 640 MPa (92.8 ksi). In exchange, 601GC SA-CG is the more ductile: elongation 50% versus 25% for 601GC-CD, and 601GC-CD is harder (230 HB vs 155 HB). 601GC SA-CG runs hotter in service (1,250°C vs 600°C continuous).

601GC SA-CGChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
601GC-CD vs 601GC SA-CG: 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-CD vs 601GC SA-CG — frequently asked
Is 601GC-CD stronger than 601GC SA-CG?
Yes. 601GC-CD has a typical yield strength of 550 MPa (79.8 ksi) against 270 MPa (39.2 ksi) for 601GC SA-CG — about 104% more. Tensile strength is 830 MPa (120 ksi) vs 640 MPa (92.8 ksi).
Which condition does FabDigit quote by default, CD or SA-CG?
ANN is the default 601GC condition in the FabDigit quote flow (neither CD nor SA-CG). 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-CD or 601GC SA-CG?
601GC-CD, by a small margin. Both rate poor for machinability — 26/100 against 21/100 for 601GC SA-CG.
