Stainless Steel S44625-ANN vs S44625-AW
Stainless Steel · S44625 temper comparison
S44625-ANN and S44625-AW are two conditions of the same stainless steel grade, S44625: ANN (annealed) versus AW (as-welded deposit). The chemistry is identical, so every difference below comes from the condition. Both yield at about 380 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). S44625-ANN is the more ductile: elongation 28% versus 15% for S44625-AW, and S44625-AW is harder (185 HB vs 175 HB).
S44625-ANNChoose it when the part is bent, formed or impact-loaded.
S44625-ANN vs S44625-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.
