Nickel Alloy 2.4889 Annealed vs 2.4889-H
Nickel Alloy · 2.4889 temper comparison
2.4889 Annealed and 2.4889-H are two conditions of the same nickel alloy grade, 2.4889: Annealed versus H (hardened). The chemistry is identical, so every difference below comes from the condition. 2.4889-H is the stronger of the two: yield strength 950 MPa (138 ksi) against 400 MPa (58 ksi) for 2.4889 Annealed, about 138% more; tensile strength follows at 1,150 MPa (167 ksi) vs 760 MPa (110 ksi). In exchange, 2.4889 Annealed is the more ductile: elongation 30% versus 4% for 2.4889-H, and 2.4889-H is harder (300 HB vs 170 HB). On the shop floor, 2.4889 Annealed welds better (65 vs 55 out of 100).

2.4889 Annealed vs 2.4889-H: 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.

2.4889 Annealed vs 2.4889-H — frequently asked
Is 2.4889-H stronger than 2.4889 Annealed?
Yes. 2.4889-H has a typical yield strength of 950 MPa (138 ksi) against 400 MPa (58 ksi) for 2.4889 Annealed — about 138% more. Tensile strength is 1,150 MPa (167 ksi) vs 760 MPa (110 ksi).
Which condition does FabDigit quote by default, Annealed or H?
Annealed is the default 2.4889 condition in the FabDigit quote flow. 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 is easier to machine, 2.4889 Annealed or 2.4889-H?
2.4889-H, by a small margin. Both rate poor for machinability — 28/100 against 22/100 for 2.4889 Annealed; for welding the order is 2.4889 Annealed first (good, 65/100) then 2.4889-H (good, 55/100).
