Nickel Alloy Inconel 693 Aged vs Inconel 693-CD
Nickel Alloy · Inconel 693 temper comparison
Inconel 693 Aged and Inconel 693-CD are two conditions of the same nickel alloy grade, Inconel 693: Aged (annealed + Aged) versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. Inconel 693-CD is the stronger of the two: yield strength 700 MPa (102 ksi) against 600 MPa (87 ksi) for Inconel 693 Aged, about 17% more. Inconel 693 Aged is harder — 290 HB against 270 HB for Inconel 693-CD — which matters for wear surfaces and threads. Inconel 693 Aged runs hotter in service (1,100°C vs 600°C continuous).
Inconel 693 AgedChoose it when surface hardness matters, or when the part sees heat.
Inconel 693-CDChoose it when strength drives the design.
Inconel 693 Aged vs Inconel 693-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.

Inconel 693 Aged vs Inconel 693-CD — frequently asked
Is Inconel 693-CD stronger than Inconel 693 Aged?
Yes. Inconel 693-CD has a typical yield strength of 700 MPa (102 ksi) against 600 MPa (87 ksi) for Inconel 693 Aged — about 17% more. Tensile strength is 950 MPa (138 ksi) vs 950 MPa (138 ksi).
Which condition does FabDigit quote by default, Aged or CD?
ANN is the default Inconel 693 condition in the FabDigit quote flow (neither Aged 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, Inconel 693 Aged or Inconel 693-CD?
Inconel 693-CD. Its machinability rates poor (18/100) against not recommended (13/100) for Inconel 693 Aged; for welding the order is Inconel 693-CD first (fair, 50/100) then Inconel 693 Aged (fair, 45/100).
