Stainless Steel S44800 Annealed vs S44800 As Welded
Stainless Steel · S44800 temper comparison
S44800 Annealed and S44800 As Welded are two conditions of the same stainless steel grade, S44800: Annealed versus As Welded (as-welded deposit). The chemistry is identical, so every difference below comes from the condition. Both yield at about 480 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). S44800 Annealed is the more ductile: elongation 25% versus 15% for S44800 As Welded.

S44800 Annealed vs S44800 As Welded: 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.
