Stainless Steel ER410NiMo-AW vs ER410NiMo N+T
Stainless Steel · ER410NiMo temper comparison
ER410NiMo-AW and ER410NiMo N+T are two conditions of the same stainless steel grade, ER410NiMo: AW (as-welded deposit) versus N+T (normalized and tempered). The chemistry is identical, so every difference below comes from the condition. ER410NiMo-AW is the stronger of the two: yield strength 830 MPa (120 ksi) against 680 MPa (98.6 ksi) for ER410NiMo N+T, about 22% more; tensile strength follows at 950 MPa (138 ksi) vs 830 MPa (120 ksi). In exchange, ER410NiMo N+T is the more ductile: elongation 20% versus 14% for ER410NiMo-AW, and ER410NiMo-AW is harder (355 HB vs 265 HB). ER410NiMo N+T runs hotter in service (450°C vs 400°C continuous). On the shop floor, ER410NiMo N+T machines more easily (fair vs poor).

ER410NiMo-AW vs ER410NiMo N+T: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all stainless steel 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.
