Stainless Steel N08026 Annealed vs N08026-AW
Stainless Steel · N08026 temper comparison
N08026 Annealed and N08026-AW are two conditions of the same stainless steel grade, N08026: Annealed versus AW (as-welded deposit). The chemistry is identical, so every difference below comes from the condition. N08026-AW is the stronger of the two: yield strength 330 MPa (47.9 ksi) against 310 MPa (45 ksi) for N08026 Annealed, about 6% more. In exchange, N08026 Annealed is the more ductile: elongation 45% versus 35% for N08026-AW, and N08026-AW is harder (185 HB vs 170 HB). N08026 Annealed runs hotter in service (500°C vs 450°C continuous).
N08026 AnnealedChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
N08026-AWChoose it when strength drives the design.
N08026 Annealed vs N08026-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.
