ASTM A302 Alloy Steel vs. Grade 6 Titanium

ASTM A302 alloy steel belongs to the iron alloys classification, while grade 6 titanium belongs to the titanium alloys. There are 30 material properties with values for both materials. Properties with values for just one material (2, in this case) are not shown.

For each property being compared, the top bar is ASTM A302 alloy steel and the bottom bar is grade 6 titanium.
