Titanium Ti Grade 30 Annealed vs Ti Grade 30 AS-WELDED

Titanium · Ti Grade 30 temper comparison

Ti Grade 30 Annealed and Ti Grade 30 AS-WELDED are two conditions of the same titanium grade, Ti Grade 30: Annealed versus AS-WELDED (as-welded deposit). The chemistry is identical, so every difference below comes from the condition. Ti Grade 30 AS-WELDED is the stronger of the two: yield strength 350 MPa (50.8 ksi) against 330 MPa (47.9 ksi) for Ti Grade 30 Annealed, about 6% more. In exchange, Ti Grade 30 Annealed is the more ductile: elongation 28% versus 20% for Ti Grade 30 AS-WELDED, and Ti Grade 30 AS-WELDED is harder (175 HB vs 160 HB).
