Stainless Steel 1.4887 CAST-C vs 1.4887-CD
Stainless Steel · 1.4887 temper comparison
1.4887 CAST-C and 1.4887-CD are two conditions of the same stainless steel grade, 1.4887: CAST-C (as-Cast, centrifugally cast tube) 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 240 MPa (34.8 ksi) for 1.4887 CAST-C, about 75% more; tensile strength follows at 680 MPa (98.6 ksi) vs 480 MPa (69.6 ksi). 1.4887-CD is the more ductile: elongation 20% versus 12% for 1.4887 CAST-C, and 1.4887-CD is harder (215 HB vs 185 HB).
1.4887-CDChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
1.4887 CAST-C 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 CAST-C vs 1.4887-CD — frequently asked
Is 1.4887-CD stronger than 1.4887 CAST-C?
Yes. 1.4887-CD has a typical yield strength of 420 MPa (60.9 ksi) against 240 MPa (34.8 ksi) for 1.4887 CAST-C — about 75% more. Tensile strength is 680 MPa (98.6 ksi) vs 480 MPa (69.6 ksi).
Which condition does FabDigit quote by default, CAST-C or CD?
SA is the default 1.4887 condition in the FabDigit quote flow (neither CAST-C 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 CAST-C or 1.4887-CD?
1.4887-CD, by a small margin. Both rate poor for machinability — 27/100 against 20/100 for 1.4887 CAST-C; for welding the order is 1.4887-CD first (good, 55/100) then 1.4887 CAST-C (fair, 50/100).
