Titanium Ti Grade 28 Annealed vs Ti Grade 28 TransBeta

Titanium · Ti Grade 28 temper comparison

Ti Grade 28 Annealed and Ti Grade 28 TransBeta are two conditions of the same titanium grade, Ti Grade 28: Annealed versus TransBeta (transformed Beta). The chemistry is identical, so every difference below comes from the condition. Ti Grade 28 TransBeta is the stronger of the two: yield strength 595 MPa (86.3 ksi) against 550 MPa (79.8 ksi) for Ti Grade 28 Annealed, about 8% more. In exchange, Ti Grade 28 Annealed is the more ductile: elongation 22% versus 12% for Ti Grade 28 TransBeta.
