Nickel Alloy Hastelloy C276 As Welded vs Hastelloy C276 Solution Annealed
Nickel Alloy · Hastelloy C276 temper comparison
Hastelloy C276 As Welded and Hastelloy C276 Solution Annealed are two conditions of the same nickel alloy grade, Hastelloy C276: As Welded (as-welded deposit) versus Solution Annealed. The chemistry is identical, so every difference below comes from the condition. Hastelloy C276 As Welded is the stronger of the two: yield strength 490 MPa (71.1 ksi) against 360 MPa (52.2 ksi) for Hastelloy C276 Solution Annealed, about 36% more. In exchange, Hastelloy C276 Solution Annealed is the more ductile: elongation 60% versus 40% for Hastelloy C276 As Welded.
Hastelloy C276 As WeldedChoose it when strength drives the design.
Hastelloy C276 Solution AnnealedChoose it when the part is bent, formed or impact-loaded.
Hastelloy C276 As Welded vs Hastelloy C276 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.
