Nickel 270 Annealed vs Nickel 270 Cold Drawn
Nickel Alloy · Nickel 270 temper comparison
Nickel 270 Annealed and Nickel 270 Cold Drawn are two conditions of the same nickel alloy grade, Nickel 270: Annealed versus Cold Drawn. The chemistry is identical, so every difference below comes from the condition. Nickel 270 Cold Drawn is the stronger of the two: yield strength 420 MPa (60.9 ksi) against 105 MPa (15.2 ksi) for Nickel 270 Annealed, about 4.0 times as much; tensile strength follows at 500 MPa (72.5 ksi) vs 345 MPa (50 ksi). In exchange, Nickel 270 Annealed is the more ductile: elongation 50% versus 15% for Nickel 270 Cold Drawn, and Nickel 270 Cold Drawn is harder (130 HB vs 45 HB).

Nickel 270 Annealed vs Nickel 270 Cold Drawn: 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.
