Stainless Steel N08024-ANN vs N08024-CW
Stainless Steel · N08024 temper comparison
N08024-ANN and N08024-CW are two conditions of the same stainless steel grade, N08024: ANN (annealed) versus CW (cold worked). The chemistry is identical, so every difference below comes from the condition. N08024-CW is the stronger of the two: yield strength 590 MPa (85.6 ksi) against 290 MPa (42.1 ksi) for N08024-ANN, about 103% more; tensile strength follows at 790 MPa (115 ksi) vs 620 MPa (89.9 ksi). In exchange, N08024-ANN is the more ductile: elongation 45% versus 22% for N08024-CW, and N08024-CW is harder (250 HB vs 180 HB).
N08024-ANNChoose it when the part is bent, formed or impact-loaded.
N08024-CWChoose it when strength drives the design.
N08024-ANN vs N08024-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.
