Stainless Steel S33425 Annealed vs S33425-CD
Stainless Steel · S33425 temper comparison
S33425 Annealed and S33425-CD are two conditions of the same stainless steel grade, S33425: Annealed versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. S33425-CD is the stronger of the two: yield strength 500 MPa (72.5 ksi) against 275 MPa (39.9 ksi) for S33425 Annealed, about 82% more; tensile strength follows at 720 MPa (104 ksi) vs 585 MPa (84.8 ksi). In exchange, S33425 Annealed is the more ductile: elongation 45% versus 25% for S33425-CD, and S33425-CD is harder (210 HB vs 150 HB).
S33425 AnnealedChoose it when the part is bent, formed or impact-loaded.
S33425-CDChoose it when strength drives the design.
S33425 Annealed vs S33425-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.
