Stainless Steel S44725 Annealed vs S44725-AW
Stainless Steel · S44725 temper comparison
S44725 Annealed and S44725-AW are two conditions of the same stainless steel grade, S44725: Annealed versus AW (as-welded deposit). The chemistry is identical, so every difference below comes from the condition. S44725 Annealed is the stronger of the two: yield strength 480 MPa (69.6 ksi) against 450 MPa (65.3 ksi) for S44725-AW, about 7% more. S44725 Annealed is the more ductile: elongation 27% versus 18% for S44725-AW, and S44725-AW is harder (190 HB vs 180 HB).
S44725 AnnealedChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
S44725 Annealed vs S44725-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.
