Stainless Steel N08028-CD vs N08028-CW
Stainless Steel · N08028 temper comparison
N08028-CD and N08028-CW are two conditions of the same stainless steel grade, N08028: CD (cold drawn) versus CW (cold worked). The chemistry is identical, so every difference below comes from the condition. N08028-CW is the stronger of the two: yield strength 570 MPa (82.7 ksi) against 490 MPa (71.1 ksi) for N08028-CD, about 16% more; tensile strength follows at 780 MPa (113 ksi) vs 720 MPa (104 ksi). In exchange, N08028-CD is the more ductile: elongation 25% versus 20% for N08028-CW, and N08028-CW is harder (250 HB vs 225 HB). On the shop floor, N08028-CD welds better (very good vs good).
N08028-CDChoose it when the part is bent, formed or impact-loaded, or when it will be welded.
N08028-CWChoose it when strength drives the design.
N08028-CD vs N08028-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.

N08028-CD vs N08028-CW — frequently asked
Is N08028-CW stronger than N08028-CD?
Yes. N08028-CW has a typical yield strength of 570 MPa (82.7 ksi) against 490 MPa (71.1 ksi) for N08028-CD — about 16% more. Tensile strength is 780 MPa (113 ksi) vs 720 MPa (104 ksi).
Which condition does FabDigit quote by default, CD or CW?
SA is the default N08028 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 welds better, N08028-CD or N08028-CW?
N08028-CD. Its weldability rates very good (75/100) against good (65/100) for N08028-CW.
