Nickel Alloy Alloy 333 vs Haynes 282
Nickel Alloy · grade comparison
Nickel Alloy Alloy 333 and Haynes 282 are both nickel alloy grades. Haynes 282 is the stronger of the two: yield strength 550 MPa (79.8 ksi) against 310 MPa (45 ksi) for Alloy 333, about 77% more; tensile strength follows at 1,010 MPa (146 ksi) vs 690 MPa (100 ksi). Haynes 282 is harder — 200 HB against 190 HB for Alloy 333 — which matters for wear surfaces and threads. Haynes 282 is stiffer (217 GPa vs 203 GPa) and Alloy 333 runs hotter in service (1,100°C vs 850°C continuous). On the shop floor, Haynes 282 welds better (excellent vs very good).

Haynes 282Choose it when strength drives the design, or when surface hardness matters.
Alloy 333 vs Haynes 282: 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.

Alloy 333 vs Haynes 282 — frequently asked
Is Haynes 282 stronger than Alloy 333?
Yes. Haynes 282 has a typical yield strength of 550 MPa (79.8 ksi) against 310 MPa (45 ksi) for Alloy 333 — about 77% more. Tensile strength is 1,010 MPa (146 ksi) vs 690 MPa (100 ksi).
Which is cheaper, Alloy 333 or Haynes 282?
Both sit in the same relative cost tier ($$$$, high); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, Alloy 333 or Haynes 282?
Alloy 333, by a small margin. Both rate poor for machinability — 25/100 against 20/100 for Haynes 282; for welding the order is Haynes 282 first (excellent, 88/100) then Alloy 333 (very good, 78/100).
