Stainless Steel S32003 Annealed vs S32003-CD
Stainless Steel · S32003 temper comparison
S32003 Annealed and S32003-CD are two conditions of the same stainless steel grade, S32003: Annealed versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. S32003-CD is the stronger of the two: yield strength 650 MPa (94.3 ksi) against 530 MPa (76.9 ksi) for S32003 Annealed, about 23% more; tensile strength follows at 820 MPa (119 ksi) vs 730 MPa (106 ksi). In exchange, S32003 Annealed is the more ductile: elongation 32% versus 22% for S32003-CD, and S32003-CD is harder (270 HB vs 230 HB).
S32003 AnnealedChoose it when the part is bent, formed or impact-loaded.
S32003-CDChoose it when strength drives the design.
S32003 Annealed vs S32003-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.
