Stainless Steel 308L As Welded vs 308L Cold Drawn
Stainless Steel · 308L temper comparison
308L As Welded and 308L Cold Drawn are two conditions of the same stainless steel grade, 308L: As Welded (as-welded deposit) versus Cold Drawn. The chemistry is identical, so every difference below comes from the condition. 308L Cold Drawn is the stronger of the two: yield strength 600 MPa (87 ksi) against 400 MPa (58 ksi) for 308L As Welded, about 50% more; tensile strength follows at 800 MPa (116 ksi) vs 580 MPa (84.1 ksi). In exchange, 308L As Welded is the more ductile: elongation 40% versus 25% for 308L Cold Drawn, and 308L Cold Drawn is harder (215 HB vs 170 HB). 308L As Welded runs hotter in service (760°C vs 400°C continuous).
308L As WeldedChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
308L Cold DrawnChoose it when strength drives the design.
308L As Welded vs 308L Cold Drawn: 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.

308L As Welded vs 308L Cold Drawn — frequently asked
Is 308L Cold Drawn stronger than 308L As Welded?
Yes. 308L Cold Drawn has a typical yield strength of 600 MPa (87 ksi) against 400 MPa (58 ksi) for 308L As Welded — about 50% more. Tensile strength is 800 MPa (116 ksi) vs 580 MPa (84.1 ksi).
Which condition does FabDigit quote by default, As Welded or Cold Drawn?
Annealed is the default 308L condition in the FabDigit quote flow (neither As Welded nor Cold Drawn). 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, 308L As Welded or 308L Cold Drawn?
308L Cold Drawn, by a small margin. Both rate fair for machinability — 45/100 against 40/100 for 308L As Welded.
