Nickel Alloy 2.4889 Annealed vs 2.4889 HRAnn
Nickel Alloy · 2.4889 temper comparison
2.4889 Annealed and 2.4889 HRAnn are two conditions of the same nickel alloy grade, 2.4889: Annealed versus HRAnn (hot rolled + annealed bar / rod). The chemistry is identical, so every difference below comes from the condition. 2.4889 Annealed is the stronger of the two: yield strength 400 MPa (58 ksi) against 350 MPa (50.8 ksi) for 2.4889 HRAnn, about 14% more; tensile strength follows at 760 MPa (110 ksi) vs 720 MPa (104 ksi). In exchange, 2.4889 HRAnn is the more ductile: elongation 35% versus 30% for 2.4889 Annealed, and 2.4889 Annealed is harder (170 HB vs 160 HB).
2.4889 AnnealedChoose it when strength drives the design.
2.4889 HRAnnChoose it when the part is bent, formed or impact-loaded.
2.4889 Annealed vs 2.4889 HRAnn: 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.
