Titanium Ti Grade 16 Annealed vs Ti Grade 16-Gr16H
Titanium · Ti Grade 16 temper comparison
Ti Grade 16 Annealed and Ti Grade 16-Gr16H are two conditions of the same titanium grade, Ti Grade 16: Annealed versus Gr16H (grade 16H). The chemistry is identical, so every difference below comes from the condition. Ti Grade 16-Gr16H is the stronger of the two: yield strength 400 MPa (58 ksi) against 380 MPa (55.1 ksi) for Ti Grade 16 Annealed, about 5% more; tensile strength follows at 520 MPa (75.4 ksi) vs 460 MPa (66.7 ksi). Ti Grade 16-Gr16H is harder — 165 HB against 150 HB for Ti Grade 16 Annealed — which matters for wear surfaces and threads.
Ti Grade 16-Gr16HChoose it when strength drives the design, or when surface hardness matters.
Ti Grade 16 Annealed vs Ti Grade 16-Gr16H: 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.
