Solution Treated and Aged Titanium 15-3-3-3
Solution treated and aged titanium 15-3-3-3 is a type of titanium 15-3-3-3. The graph bars on the material properties cards below compare solution treated and aged titanium 15-3-3-3 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.
