Stainless Steel S32050 Annealed vs S32050-CD
Stainless Steel · S32050 temper comparison
S32050 Annealed and S32050-CD are two conditions of the same stainless steel grade, S32050: Annealed versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. S32050-CD is the stronger of the two: yield strength 690 MPa (100 ksi) against 400 MPa (58 ksi) for S32050 Annealed, about 73% more; tensile strength follows at 900 MPa (131 ksi) vs 780 MPa (113 ksi). In exchange, S32050 Annealed is the more ductile: elongation 48% versus 28% for S32050-CD, and S32050-CD is harder (260 HB vs 200 HB). S32050 Annealed runs hotter in service (425°C vs 300°C continuous).
S32050 AnnealedChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
S32050-CDChoose it when strength drives the design.
S32050 Annealed vs S32050-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.
