Stainless Steel 1.4887-AW vs 1.4887-CD
Stainless Steel · 1.4887 temper comparison
1.4887-AW and 1.4887-CD are two conditions of the same stainless steel grade, 1.4887: AW (as-welded deposit) versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. 1.4887-CD is the stronger of the two: yield strength 420 MPa (60.9 ksi) against 260 MPa (37.7 ksi) for 1.4887-AW, about 62% more; tensile strength follows at 680 MPa (98.6 ksi) vs 470 MPa (68.2 ksi). 1.4887-CD is the more ductile: elongation 20% versus 15% for 1.4887-AW, and 1.4887-CD is harder (215 HB vs 180 HB).
1.4887-CDChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
1.4887-AW vs 1.4887-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.

1.4887-AW vs 1.4887-CD — frequently asked
Is 1.4887-CD stronger than 1.4887-AW?
Yes. 1.4887-CD has a typical yield strength of 420 MPa (60.9 ksi) against 260 MPa (37.7 ksi) for 1.4887-AW — about 62% more. Tensile strength is 680 MPa (98.6 ksi) vs 470 MPa (68.2 ksi).
Which condition does FabDigit quote by default, AW or CD?
SA is the default 1.4887 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, 1.4887-AW or 1.4887-CD?
1.4887-CD, by a small margin. Both rate poor for machinability — 27/100 against 22/100 for 1.4887-AW.
