Stainless Steel 310L NAG Annealed vs 310L NAG-AW
Stainless Steel · 310L NAG temper comparison
310L NAG Annealed and 310L NAG-AW are two conditions of the same stainless steel grade, 310L NAG: Annealed versus AW (as-welded deposit). The chemistry is identical, so every difference below comes from the condition. 310L NAG-AW is the stronger of the two: yield strength 330 MPa (47.9 ksi) against 305 MPa (44.2 ksi) for 310L NAG Annealed, about 8% more. In exchange, 310L NAG Annealed is the more ductile: elongation 48% versus 30% for 310L NAG-AW, and 310L NAG-AW is harder (180 HB vs 165 HB). 310L NAG Annealed runs hotter in service (600°C vs 550°C continuous).
310L NAG AnnealedChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
310L NAG-AWChoose it when strength drives the design.
310L NAG Annealed vs 310L NAG-AW: 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.

310L NAG Annealed vs 310L NAG-AW — frequently asked
Is 310L NAG-AW stronger than 310L NAG Annealed?
Yes. 310L NAG-AW has a typical yield strength of 330 MPa (47.9 ksi) against 305 MPa (44.2 ksi) for 310L NAG Annealed — about 8% more. Tensile strength is 590 MPa (85.6 ksi) vs 620 MPa (89.9 ksi).
Which condition does FabDigit quote by default, Annealed or AW?
Annealed is the default 310L NAG 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.
Which is easier to machine, 310L NAG Annealed or 310L NAG-AW?
310L NAG Annealed, by a small margin. Both rate poor for machinability — 30/100 against 25/100 for 310L NAG-AW; for welding the order is 310L NAG Annealed first (very good, 70/100) then 310L NAG-AW (good, 65/100).
