Stainless Steel S32950 Annealed vs S32950-AW
Stainless Steel · S32950 temper comparison
S32950 Annealed and S32950-AW are two conditions of the same stainless steel grade, S32950: Annealed versus AW (as-welded deposit). The chemistry is identical, so every difference below comes from the condition. Both yield at about 560 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (Annealed versus as-welded deposit). S32950 Annealed is the more ductile: elongation 27% versus 22% for S32950-AW.
S32950 AnnealedChoose it when the part is bent, formed or impact-loaded.
S32950 Annealed vs S32950-AW: 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.
