Stainless Steel 310MoLN As Welded vs 310MoLN-CD
Stainless Steel · 310MoLN temper comparison
310MoLN As Welded and 310MoLN-CD are two conditions of the same stainless steel grade, 310MoLN: As Welded (as-welded deposit) versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. 310MoLN-CD is the stronger of the two: yield strength 510 MPa (74 ksi) against 330 MPa (47.9 ksi) for 310MoLN As Welded, about 55% more; tensile strength follows at 720 MPa (104 ksi) vs 590 MPa (85.6 ksi). In exchange, 310MoLN As Welded is the more ductile: elongation 35% versus 25% for 310MoLN-CD, and 310MoLN-CD is harder (220 HB vs 180 HB). 310MoLN As Welded runs hotter in service (550°C vs 425°C continuous).
310MoLN As WeldedChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
310MoLN-CDChoose it when strength drives the design.
310MoLN As Welded vs 310MoLN-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.

310MoLN As Welded vs 310MoLN-CD — frequently asked
Is 310MoLN-CD stronger than 310MoLN As Welded?
Yes. 310MoLN-CD has a typical yield strength of 510 MPa (74 ksi) against 330 MPa (47.9 ksi) for 310MoLN As Welded — about 55% more. Tensile strength is 720 MPa (104 ksi) vs 590 MPa (85.6 ksi).
Which condition does FabDigit quote by default, As Welded or CD?
Annealed is the default 310MoLN condition in the FabDigit quote flow (neither As Welded 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, 310MoLN As Welded or 310MoLN-CD?
310MoLN-CD. Its machinability rates fair (35/100) against poor (27/100) for 310MoLN As Welded.
