Stainless Steel S35115 Annealed vs S35115-AW
Stainless Steel · S35115 temper comparison
S35115 Annealed and S35115-AW are two conditions of the same stainless steel grade, S35115: Annealed versus AW (as-welded deposit). The chemistry is identical, so every difference below comes from the condition. S35115-AW is the stronger of the two: yield strength 280 MPa (40.6 ksi) against 265 MPa (38.4 ksi) for S35115 Annealed, about 6% more. In exchange, S35115 Annealed is the more ductile: elongation 45% versus 35% for S35115-AW, and S35115-AW is harder (175 HB vs 165 HB). S35115 Annealed runs hotter in service (500°C vs 450°C continuous).
S35115 AnnealedChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
S35115-AWChoose it when strength drives the design.
S35115 Annealed vs S35115-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.
