Stainless Steel S34565-CD vs S34565-CW
Stainless Steel · S34565 temper comparison
S34565-CD and S34565-CW are two conditions of the same stainless steel grade, S34565: CD (cold drawn) versus CW (cold worked). The chemistry is identical, so every difference below comes from the condition. S34565-CW is the stronger of the two: yield strength 900 MPa (131 ksi) against 700 MPa (102 ksi) for S34565-CD, about 29% more; tensile strength follows at 1,100 MPa (160 ksi) vs 950 MPa (138 ksi). In exchange, S34565-CD is the more ductile: elongation 25% versus 12% for S34565-CW, and S34565-CW is harder (320 HB vs 280 HB). S34565-CD runs hotter in service (400°C vs 300°C continuous).
S34565-CDChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
S34565-CWChoose it when strength drives the design.
S34565-CD vs S34565-CW: 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.

S34565-CD vs S34565-CW — frequently asked
Is S34565-CW stronger than S34565-CD?
Yes. S34565-CW has a typical yield strength of 900 MPa (131 ksi) against 700 MPa (102 ksi) for S34565-CD — about 29% more. Tensile strength is 1,100 MPa (160 ksi) vs 950 MPa (138 ksi).
Which condition does FabDigit quote by default, CD or CW?
SA is the default S34565 condition in the FabDigit quote flow (neither CD nor CW). 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, S34565-CD or S34565-CW?
S34565-CD, by a small margin. Both rate poor for machinability — 24/100 against 16/100 for S34565-CW; for welding the order is S34565-CD first (good, 68/100) then S34565-CW (good, 60/100).
