Nickel Alloy Haynes 282 vs Waspaloy
Nickel Alloy · grade comparison
Nickel Alloy Haynes 282 and Waspaloy are both nickel alloy grades. Haynes 282 is the stronger of the two: yield strength 550 MPa (79.8 ksi) against 520 MPa (75.4 ksi) for Waspaloy, about 6% more; tensile strength follows at 1,010 MPa (146 ksi) vs 930 MPa (135 ksi). Haynes 282 is the more ductile: elongation 55% versus 45% for Waspaloy, and Waspaloy is harder (250 HB vs 200 HB). Haynes 282 runs hotter in service (850°C vs 650°C continuous). On the shop floor, Haynes 282 welds better (excellent vs fair) and Waspaloy sits in a lower cost tier (premium, $$$) than Haynes 282 (high, $$$$).
Haynes 282Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
WaspaloyChoose it when cost is the deciding factor.
Haynes 282 vs Waspaloy: 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.
