Nickel Alloy Hastelloy X Cold Worked vs Hastelloy X Solution Annealed
Nickel Alloy · Hastelloy X temper comparison
Hastelloy X Cold Worked and Hastelloy X Solution Annealed are two conditions of the same nickel alloy grade, Hastelloy X: Cold Worked versus Solution Annealed. The chemistry is identical, so every difference below comes from the condition. Hastelloy X Cold Worked is the stronger of the two: yield strength 800 MPa (116 ksi) against 360 MPa (52.2 ksi) for Hastelloy X Solution Annealed, about 122% more; tensile strength follows at 1,000 MPa (145 ksi) vs 755 MPa (110 ksi). In exchange, Hastelloy X Solution Annealed is the more ductile: elongation 43% versus 12% for Hastelloy X Cold Worked, and Hastelloy X Cold Worked is harder (293 HB vs 195 HB). Hastelloy X Solution Annealed runs hotter in service (1,150°C vs 550°C continuous). On the shop floor, Hastelloy X Solution Annealed welds better (excellent vs very good).

Hastelloy X Cold Worked vs Hastelloy X 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.
