Stainless Steel S32615 Annealed vs S32615-AW
Stainless Steel · S32615 temper comparison
S32615 Annealed and S32615-AW are two conditions of the same stainless steel grade, S32615: Annealed versus AW (as-welded deposit). The chemistry is identical, so every difference below comes from the condition. S32615-AW is the stronger of the two: yield strength 330 MPa (47.9 ksi) against 300 MPa (43.5 ksi) for S32615 Annealed, about 10% more. In exchange, S32615 Annealed is the more ductile: elongation 40% versus 28% for S32615-AW, and S32615-AW is harder (195 HB vs 180 HB).
S32615 AnnealedChoose it when the part is bent, formed or impact-loaded.
S32615-AWChoose it when strength drives the design.
S32615 Annealed vs S32615-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.
