Nickel Alloy Inconel 693-ANN vs Inconel 693-CD
Nickel Alloy · Inconel 693 temper comparison
Inconel 693-ANN and Inconel 693-CD are two conditions of the same nickel alloy grade, Inconel 693: ANN (annealed) 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 400 MPa (58 ksi) for Inconel 693-ANN, about 75% more; tensile strength follows at 950 MPa (138 ksi) vs 790 MPa (115 ksi). In exchange, Inconel 693-ANN is the more ductile: elongation 45% versus 25% for Inconel 693-CD, and Inconel 693-CD is harder (270 HB vs 195 HB). Inconel 693-ANN runs hotter in service (1,100°C vs 600°C continuous).
Inconel 693-ANNChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
Inconel 693-CDChoose it when strength drives the design.
Inconel 693-ANN 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.
