Nickel Alloy ENiCrMo-3-AW vs ENiCrMo-3-SR
Nickel Alloy · ENiCrMo-3 temper comparison
ENiCrMo-3-AW and ENiCrMo-3-SR are two conditions of the same nickel alloy grade, ENiCrMo-3: AW (as-welded deposit) versus SR (stress relieved). The chemistry is identical, so every difference below comes from the condition. ENiCrMo-3-AW is the stronger of the two: yield strength 520 MPa (75.4 ksi) against 460 MPa (66.7 ksi) for ENiCrMo-3-SR, about 13% more; tensile strength follows at 800 MPa (116 ksi) vs 760 MPa (110 ksi). ENiCrMo-3-AW is harder — 220 HB against 205 HB for ENiCrMo-3-SR — which matters for wear surfaces and threads.
ENiCrMo-3-AWChoose it when strength drives the design, or when surface hardness matters.
ENiCrMo-3-AW vs ENiCrMo-3-SR: 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.

ENiCrMo-3-AW vs ENiCrMo-3-SR — frequently asked
Is ENiCrMo-3-AW stronger than ENiCrMo-3-SR?
Yes. ENiCrMo-3-AW has a typical yield strength of 520 MPa (75.4 ksi) against 460 MPa (66.7 ksi) for ENiCrMo-3-SR — about 13% more. Tensile strength is 800 MPa (116 ksi) vs 760 MPa (110 ksi).
Which condition does FabDigit quote by default, AW or SR?
AW is the default ENiCrMo-3 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.
When should I choose ENiCrMo-3-AW over ENiCrMo-3-SR?
Pick ENiCrMo-3-AW when strength drives the design, or when surface hardness matters.
