Stainless Steel 1.4864-ANN vs 1.4864 CW-1/4H
Stainless Steel · 1.4864 temper comparison
1.4864-ANN and 1.4864 CW-1/4H are two conditions of the same stainless steel grade, 1.4864: ANN (annealed) 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 255 MPa (37 ksi) for 1.4864-ANN, about 104% more; tensile strength follows at 760 MPa (110 ksi) vs 585 MPa (84.8 ksi). In exchange, 1.4864-ANN is the more ductile: elongation 43% versus 20% for 1.4864 CW-1/4H, and 1.4864 CW-1/4H is harder (230 HB vs 150 HB).

1.4864-ANN 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-ANN vs 1.4864 CW-1/4H — frequently asked
Is 1.4864 CW-1/4H stronger than 1.4864-ANN?
Yes. 1.4864 CW-1/4H has a typical yield strength of 520 MPa (75.4 ksi) against 255 MPa (37 ksi) for 1.4864-ANN — about 104% more. Tensile strength is 760 MPa (110 ksi) vs 585 MPa (84.8 ksi).
Which condition does FabDigit quote by default, ANN or CW-1/4H?
ANN is the default 1.4864 condition in the FabDigit quote flow. 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-ANN or 1.4864 CW-1/4H?
1.4864-ANN, by a small margin. Both rate poor for machinability — 28/100 against 22/100 for 1.4864 CW-1/4H; for welding the order is 1.4864-ANN first (very good, 70/100) then 1.4864 CW-1/4H (good, 65/100).
