Titanium Ti Grade 25 Annealed vs Ti Grade 25 As Welded
Titanium · Ti Grade 25 temper comparison
Ti Grade 25 Annealed and Ti Grade 25 As Welded are two conditions of the same titanium grade, Ti Grade 25: Annealed versus As Welded (as-welded deposit). The chemistry is identical, so every difference below comes from the condition. Both yield at about 880 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). Ti Grade 25 Annealed is the more ductile: elongation 14% versus 7% for Ti Grade 25 As Welded, and Ti Grade 25 As Welded is harder (350 HB vs 330 HB). Ti Grade 25 Annealed runs hotter in service (400°C vs 350°C continuous).

Ti Grade 25 Annealed vs Ti Grade 25 As Welded: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all titanium 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.
