Solution-Treated and Aged (High Strength) Grade 19 Titanium

High strength grade 19 titanium is grade 19 titanium in the annealed and aged condition. It has the highest strength and lowest ductility compared to the other variants of grade 19 titanium. The graph bars on the material properties cards below compare high strength grade 19 titanium to: wrought titaniums (top), all titanium alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.
