Nickel Alloy Inconel 718 Cold Drawn vs Inconel 718 Solution Annealed
Nickel Alloy · Inconel 718 temper comparison
Inconel 718 Cold Drawn and Inconel 718 Solution Annealed are two conditions of the same nickel alloy grade, Inconel 718: Cold Drawn versus Solution Annealed. The chemistry is identical, so every difference below comes from the condition. Inconel 718 Cold Drawn is the stronger of the two: yield strength 1,050 MPa (152 ksi) against 550 MPa (79.8 ksi) for Inconel 718 Solution Annealed, about 91% more; tensile strength follows at 1,250 MPa (181 ksi) vs 965 MPa (140 ksi). In exchange, Inconel 718 Solution Annealed is the more ductile: elongation 45% versus 12% for Inconel 718 Cold Drawn, and Inconel 718 Cold Drawn is harder (353 HB vs 200 HB). On the shop floor, Inconel 718 Solution Annealed welds better (very good vs good).

Inconel 718 Cold Drawn vs Inconel 718 Solution Annealed: 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.
