Nickel Alloy ENiCrMo-1-AW vs ENiCrMo-1-SR
Nickel Alloy · ENiCrMo-1 temper comparison
ENiCrMo-1-AW and ENiCrMo-1-SR are two conditions of the same nickel alloy grade, ENiCrMo-1: AW (as-welded deposit) versus SR (stress relieved). The chemistry is identical, so every difference below comes from the condition. ENiCrMo-1-AW is the stronger of the two: yield strength 450 MPa (65.3 ksi) against 400 MPa (58 ksi) for ENiCrMo-1-SR, about 13% more. ENiCrMo-1-AW is harder — 195 HB against 180 HB for ENiCrMo-1-SR — which matters for wear surfaces and threads.
ENiCrMo-1-AWChoose it when strength drives the design, or when surface hardness matters.
ENiCrMo-1-AW vs ENiCrMo-1-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-1-AW vs ENiCrMo-1-SR — frequently asked
Is ENiCrMo-1-AW stronger than ENiCrMo-1-SR?
Yes. ENiCrMo-1-AW has a typical yield strength of 450 MPa (65.3 ksi) against 400 MPa (58 ksi) for ENiCrMo-1-SR — about 13% more. Tensile strength is 690 MPa (100 ksi) vs 660 MPa (95.7 ksi).
Which condition does FabDigit quote by default, AW or SR?
AW is the default ENiCrMo-1 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-1-AW over ENiCrMo-1-SR?
Pick ENiCrMo-1-AW when strength drives the design, or when surface hardness matters.
