Solution-treated Grade 19 Titanium vs. Solution-treated Grade 20 Titanium
Both solution-treated grade 19 titanium and solution-treated grade 20 titanium are titanium alloys. Both are furnished in the solution annealed (AT) condition. Their average alloy composition is basically identical. There are 26 material properties with values for both materials. Properties with values for just one material (3, in this case) are not shown.
For each property being compared, the top bar is solution-treated grade 19 titanium and the bottom bar is solution-treated grade 20 titanium.
