Titanium Ti Grade 32-ANN vs Ti Grade 32-STA
Titanium · Ti Grade 32 temper comparison
Ti Grade 32-ANN and Ti Grade 32-STA are two conditions of the same titanium grade, Ti Grade 32: ANN (annealed) versus STA (solution treated and aged). The chemistry is identical, so every difference below comes from the condition. Ti Grade 32-STA is the stronger of the two: yield strength 820 MPa (119 ksi) against 700 MPa (102 ksi) for Ti Grade 32-ANN, about 17% more; tensile strength follows at 900 MPa (131 ksi) vs 790 MPa (115 ksi). In exchange, Ti Grade 32-ANN is the more ductile: elongation 15% versus 10% for Ti Grade 32-STA, and Ti Grade 32-STA is harder (34 HRC vs 29 HRC). On the shop floor, Ti Grade 32-ANN welds better (excellent vs very good).

Ti Grade 32-ANN vs Ti Grade 32-STA: 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.
