Stainless Steel 310L NAG-AW vs 310L NAG-CD
Stainless Steel · 310L NAG temper comparison
310L NAG-AW and 310L NAG-CD are two conditions of the same stainless steel grade, 310L NAG: AW (as-welded deposit) versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. 310L NAG-CD is the stronger of the two: yield strength 560 MPa (81.2 ksi) against 330 MPa (47.9 ksi) for 310L NAG-AW, about 70% more; tensile strength follows at 760 MPa (110 ksi) vs 590 MPa (85.6 ksi). In exchange, 310L NAG-AW is the more ductile: elongation 30% versus 25% for 310L NAG-CD, and 310L NAG-CD is harder (230 HB vs 180 HB). 310L NAG-AW runs hotter in service (550°C vs 500°C continuous). On the shop floor, 310L NAG-CD machines more easily (fair vs poor).
310L NAG-AWChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
310L NAG-CDChoose it when strength drives the design, or when the part is machined in volume.
310L NAG-AW vs 310L NAG-CD: 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-AW vs 310L NAG-CD — frequently asked
Is 310L NAG-CD stronger than 310L NAG-AW?
Yes. 310L NAG-CD has a typical yield strength of 560 MPa (81.2 ksi) against 330 MPa (47.9 ksi) for 310L NAG-AW — about 70% more. Tensile strength is 760 MPa (110 ksi) vs 590 MPa (85.6 ksi).
Which condition does FabDigit quote by default, AW or CD?
Annealed is the default 310L NAG condition in the FabDigit quote flow (neither AW nor CD). 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-AW or 310L NAG-CD?
310L NAG-CD. Its machinability rates fair (35/100) against poor (25/100) for 310L NAG-AW.
