Nickel Alloy Alloy 22 vs Alloy 242
Nickel Alloy · grade comparison
Nickel Alloy Alloy 22 and Alloy 242 are both nickel alloy grades. Alloy 22 is the stronger of the two: yield strength 400 MPa (58 ksi) against 375 MPa (54.4 ksi) for Alloy 242, about 7% more. Alloy 22 is the more ductile: elongation 62% versus 48% for Alloy 242, and Alloy 242 is harder (215 HB vs 200 HB). Alloy 22 is lighter (8.69 g/cm³ vs 9.05 g/cm³ for Alloy 242) and Alloy 242 is stiffer (217 GPa vs 206 GPa). On the shop floor, Alloy 22 welds better (excellent vs good).
Alloy 22Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
Alloy 242Choose it when the part sees heat.
Alloy 22 vs Alloy 242: 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 22 vs Alloy 242 — frequently asked
Is Alloy 22 stronger than Alloy 242?
Yes. Alloy 22 has a typical yield strength of 400 MPa (58 ksi) against 375 MPa (54.4 ksi) for Alloy 242 — about 7% more. Tensile strength is 800 MPa (116 ksi) vs 805 MPa (117 ksi).
Which is cheaper, Alloy 22 or Alloy 242?
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 welds better, Alloy 22 or Alloy 242?
Alloy 22. Its weldability rates excellent (85/100) against good (60/100) for Alloy 242.
