Titanium Ti-6-22-22 Annealed vs Ti-6-22-22-STA
Titanium · Ti-6-22-22 temper comparison
Ti-6-22-22 Annealed and Ti-6-22-22-STA are two conditions of the same titanium grade, Ti-6-22-22: Annealed versus STA (solution treated and aged). The chemistry is identical, so every difference below comes from the condition. Ti-6-22-22-STA is the stronger of the two: yield strength 1,160 MPa (168 ksi) against 950 MPa (138 ksi) for Ti-6-22-22 Annealed, about 22% more; tensile strength follows at 1,240 MPa (180 ksi) vs 1,035 MPa (150 ksi). In exchange, Ti-6-22-22 Annealed is the more ductile: elongation 13% versus 10% for Ti-6-22-22-STA, and Ti-6-22-22-STA is harder (38 HRC vs 33 HRC).

Ti-6-22-22 Annealed vs Ti-6-22-22-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.
