Nickel Alloy Alloy 52 Full Hard vs Alloy 52 Stress Relieved
Nickel Alloy · Alloy 52 temper comparison
Alloy 52 Full Hard and Alloy 52 Stress Relieved are two conditions of the same nickel alloy grade, Alloy 52: Full Hard versus Stress Relieved. The chemistry is identical, so every difference below comes from the condition. Alloy 52 Full Hard is the stronger of the two: yield strength 830 MPa (120 ksi) against 380 MPa (55.1 ksi) for Alloy 52 Stress Relieved, about 118% more; tensile strength follows at 950 MPa (138 ksi) vs 580 MPa (84.1 ksi). In exchange, Alloy 52 Stress Relieved is the more ductile: elongation 28% versus 3% for Alloy 52 Full Hard, and Alloy 52 Full Hard is harder (295 HB vs 178 HB). Alloy 52 Full Hard is stiffer (160 GPa vs 152 GPa) and Alloy 52 Stress Relieved runs hotter in service (450°C vs 250°C continuous). On the shop floor, Alloy 52 Stress Relieved welds better (68 vs 55 out of 100).
Alloy 52 Full HardChoose it when strength drives the design.
Alloy 52 Stress RelievedChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
Alloy 52 Full Hard vs Alloy 52 Stress Relieved: 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 52 Full Hard vs Alloy 52 Stress Relieved — frequently asked
Is Alloy 52 Full Hard stronger than Alloy 52 Stress Relieved?
Yes. Alloy 52 Full Hard has a typical yield strength of 830 MPa (120 ksi) against 380 MPa (55.1 ksi) for Alloy 52 Stress Relieved — about 118% more. Tensile strength is 950 MPa (138 ksi) vs 580 MPa (84.1 ksi).
Which condition does FabDigit quote by default, Full Hard or Stress Relieved?
Annealed is the default Alloy 52 condition in the FabDigit quote flow (neither Full Hard nor Stress Relieved). 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, Alloy 52 Full Hard or Alloy 52 Stress Relieved?
Alloy 52 Full Hard. Its machinability rates fair (42/100) against poor (34/100) for Alloy 52 Stress Relieved; for welding the order is Alloy 52 Stress Relieved first (good, 68/100) then Alloy 52 Full Hard (good, 55/100).
