Stainless Steel S35115-AW vs S35115-CD
Stainless Steel · S35115 temper comparison
S35115-AW and S35115-CD are two conditions of the same stainless steel grade, S35115: AW (as-welded deposit) versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. S35115-CD is the stronger of the two: yield strength 480 MPa (69.6 ksi) against 280 MPa (40.6 ksi) for S35115-AW, about 71% more; tensile strength follows at 720 MPa (104 ksi) vs 580 MPa (84.1 ksi). In exchange, S35115-AW is the more ductile: elongation 35% versus 25% for S35115-CD, and S35115-CD is harder (220 HB vs 175 HB).
S35115-AWChoose it when the part is bent, formed or impact-loaded.
S35115-CDChoose it when strength drives the design.
S35115-AW vs S35115-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.

S35115-AW vs S35115-CD — frequently asked
Is S35115-CD stronger than S35115-AW?
Yes. S35115-CD has a typical yield strength of 480 MPa (69.6 ksi) against 280 MPa (40.6 ksi) for S35115-AW — about 71% more. Tensile strength is 720 MPa (104 ksi) vs 580 MPa (84.1 ksi).
Which condition does FabDigit quote by default, AW or CD?
Annealed is the default S35115 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, S35115-AW or S35115-CD?
S35115-CD, by a small margin. Both rate poor for machinability — 32/100 against 26/100 for S35115-AW; for welding the order is S35115-AW first (very good, 70/100) then S35115-CD (good, 65/100).
