Stainless Steel S35140-AW vs S35140-CD
Stainless Steel · S35140 temper comparison
S35140-AW and S35140-CD are two conditions of the same stainless steel grade, S35140: AW (as-welded deposit) versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. S35140-CD is the stronger of the two: yield strength 550 MPa (79.8 ksi) against 300 MPa (43.5 ksi) for S35140-AW, about 83% more; tensile strength follows at 760 MPa (110 ksi) vs 590 MPa (85.6 ksi). In exchange, S35140-AW is the more ductile: elongation 30% versus 22% for S35140-CD, and S35140-CD is harder (240 HB vs 185 HB).
S35140-AWChoose it when the part is bent, formed or impact-loaded.
S35140-CDChoose it when strength drives the design.
S35140-AW vs S35140-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.

S35140-AW vs S35140-CD — frequently asked
Is S35140-CD stronger than S35140-AW?
Yes. S35140-CD has a typical yield strength of 550 MPa (79.8 ksi) against 300 MPa (43.5 ksi) for S35140-AW — about 83% 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 S35140 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, S35140-AW or S35140-CD?
S35140-CD. Its machinability rates fair (35/100) against poor (30/100) for S35140-AW.
