Stainless Steel S32808-AW vs S32808-CD
Stainless Steel · S32808 temper comparison
S32808-AW and S32808-CD are two conditions of the same stainless steel grade, S32808: AW (as-welded deposit) versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. S32808-CD is the stronger of the two: yield strength 720 MPa (104 ksi) against 600 MPa (87 ksi) for S32808-AW, about 20% more; tensile strength follows at 900 MPa (131 ksi) vs 800 MPa (116 ksi). S32808-CD is harder — 295 HB against 275 HB for S32808-AW — which matters for wear surfaces and threads.
S32808-CDChoose it when strength drives the design, or when surface hardness matters.
S32808-AW vs S32808-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.

S32808-AW vs S32808-CD — frequently asked
Is S32808-CD stronger than S32808-AW?
Yes. S32808-CD has a typical yield strength of 720 MPa (104 ksi) against 600 MPa (87 ksi) for S32808-AW — about 20% more. Tensile strength is 900 MPa (131 ksi) vs 800 MPa (116 ksi).
Which condition does FabDigit quote by default, AW or CD?
SA is the default S32808 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 welds better, S32808-AW or S32808-CD?
S32808-AW. Its weldability rates good (55/100) against fair (50/100) for S32808-CD.
