Titanium Ti Grade 26-ANN vs Ti Grade 26-GR26H

Titanium · Ti Grade 26 temper comparison

Ti Grade 26-ANN and Ti Grade 26-GR26H are two conditions of the same titanium grade, Ti Grade 26: ANN (annealed) versus GR26H (grade 26H). The chemistry is identical, so every difference below comes from the condition. Ti Grade 26-GR26H is the stronger of the two: tensile strength 460 MPa (66.7 ksi) against 430 MPa (62.4 ksi) for Ti Grade 26-ANN, about 7% more. Ti Grade 26-GR26H is harder — 175 HV against 165 HV for Ti Grade 26-ANN — which matters for wear surfaces and threads.

Ti Grade 26-GR26HChoose it when strength drives the design, or when surface hardness matters.
