Nickel Alloy Alloy 42-H14 vs Alloy 42-H24
Nickel Alloy · Alloy 42 temper comparison
Alloy 42-H14 and Alloy 42-H24 are two conditions of the same nickel alloy grade, Alloy 42: H14 (strain hardened, half hard) versus H24 (strain hardened and partially annealed, half hard). The chemistry is identical, so every difference below comes from the condition. Alloy 42-H24 is the stronger of the two: yield strength 590 MPa (85.6 ksi) against 480 MPa (69.6 ksi) for Alloy 42-H14, about 23% more; tensile strength follows at 700 MPa (102 ksi) vs 620 MPa (89.9 ksi). In exchange, Alloy 42-H14 is the more ductile: elongation 15% versus 8% for Alloy 42-H24, and Alloy 42-H24 is harder (214 HB vs 185 HB). Alloy 42-H14 runs hotter in service (350°C vs 300°C continuous).
Alloy 42-H14Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
Alloy 42-H24Choose it when strength drives the design.
Alloy 42-H14 vs Alloy 42-H24: 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 42-H14 vs Alloy 42-H24 — frequently asked
Is Alloy 42-H24 stronger than Alloy 42-H14?
Yes. Alloy 42-H24 has a typical yield strength of 590 MPa (85.6 ksi) against 480 MPa (69.6 ksi) for Alloy 42-H14 — about 23% more. Tensile strength is 700 MPa (102 ksi) vs 620 MPa (89.9 ksi).
Which condition does FabDigit quote by default, H14 or H24?
Annealed is the default Alloy 42 condition in the FabDigit quote flow (neither H14 nor H24). The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.
Which welds better, Alloy 42-H14 or Alloy 42-H24?
Alloy 42-H14. Its weldability rates good (65/100) against good (60/100) for Alloy 42-H24.
