Nickel Alloy Hastelloy C276 Cold Worked vs Hastelloy C276 Stress Relieved
Nickel Alloy · Hastelloy C276 temper comparison
Hastelloy C276 Cold Worked and Hastelloy C276 Stress Relieved are two conditions of the same nickel alloy grade, Hastelloy C276: Cold Worked versus Stress Relieved. The chemistry is identical, so every difference below comes from the condition. Hastelloy C276 Cold Worked is the stronger of the two: yield strength 800 MPa (116 ksi) against 740 MPa (107 ksi) for Hastelloy C276 Stress Relieved, about 8% more; tensile strength follows at 1,030 MPa (149 ksi) vs 970 MPa (141 ksi). In exchange, Hastelloy C276 Stress Relieved is the more ductile: elongation 28% versus 25% for Hastelloy C276 Cold Worked, and Hastelloy C276 Cold Worked is harder (290 HB vs 272 HB). Hastelloy C276 Cold Worked runs hotter in service (650°C vs 480°C continuous).
Hastelloy C276 Cold WorkedChoose it when strength drives the design, or when the part sees heat.
Hastelloy C276 Stress RelievedChoose it when the part is bent, formed or impact-loaded.
Hastelloy C276 Cold Worked vs Hastelloy C276 Stress Relieved: 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.
