Stainless Steel S32803-ANN vs S32803-CD
Stainless Steel · S32803 temper comparison
S32803-ANN and S32803-CD are two conditions of the same stainless steel grade, S32803: ANN (annealed) versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. S32803-CD is the stronger of the two: yield strength 620 MPa (89.9 ksi) against 520 MPa (75.4 ksi) for S32803-ANN, about 19% more; tensile strength follows at 740 MPa (107 ksi) vs 640 MPa (92.8 ksi). In exchange, S32803-ANN is the more ductile: elongation 25% versus 18% for S32803-CD, and S32803-CD is harder (225 HB vs 195 HB).
S32803-ANNChoose it when the part is bent, formed or impact-loaded.
S32803-CDChoose it when strength drives the design.
S32803-ANN vs S32803-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.
