Stainless Steel S32404-CD vs S32404-SA
Stainless Steel · S32404 temper comparison
S32404-CD and S32404-SA are two conditions of the same stainless steel grade, S32404: CD (cold drawn) versus SA (solution Annealed). The chemistry is identical, so every difference below comes from the condition. S32404-CD is the stronger of the two: yield strength 650 MPa (94.3 ksi) against 510 MPa (74 ksi) for S32404-SA, about 27% more; tensile strength follows at 830 MPa (120 ksi) vs 700 MPa (102 ksi). In exchange, S32404-SA is the more ductile: elongation 30% versus 20% for S32404-CD, and S32404-CD is harder (285 HB vs 240 HB).
S32404-CDChoose it when strength drives the design.
S32404-SAChoose it when the part is bent, formed or impact-loaded.
S32404-CD vs S32404-SA: 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.
