Stainless Steel 1.4864-CD vs 1.4864 CW-1/4H
Stainless Steel · 1.4864 temper comparison
1.4864-CD and 1.4864 CW-1/4H are two conditions of the same stainless steel grade, 1.4864: CD (cold drawn) versus CW-1/4H (cold Worked, 1/4 Hard). The chemistry is identical, so every difference below comes from the condition. 1.4864 CW-1/4H is the stronger of the two: yield strength 520 MPa (75.4 ksi) against 450 MPa (65.3 ksi) for 1.4864-CD, about 16% more; tensile strength follows at 760 MPa (110 ksi) vs 700 MPa (102 ksi). In exchange, 1.4864-CD is the more ductile: elongation 28% versus 20% for 1.4864 CW-1/4H, and 1.4864 CW-1/4H is harder (230 HB vs 200 HB). On the shop floor, 1.4864-CD machines more easily (33 vs 22 out of 100).

1.4864-CD vs 1.4864 CW-1/4H: 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.

1.4864-CD vs 1.4864 CW-1/4H — frequently asked
Is 1.4864 CW-1/4H stronger than 1.4864-CD?
Yes. 1.4864 CW-1/4H has a typical yield strength of 520 MPa (75.4 ksi) against 450 MPa (65.3 ksi) for 1.4864-CD — about 16% more. Tensile strength is 760 MPa (110 ksi) vs 700 MPa (102 ksi).
Which condition does FabDigit quote by default, CD or CW-1/4H?
ANN is the default 1.4864 condition in the FabDigit quote flow (neither CD nor CW-1/4H). 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, 1.4864-CD or 1.4864 CW-1/4H?
1.4864-CD, by a small margin. Both rate poor for machinability — 33/100 against 22/100 for 1.4864 CW-1/4H.
