ASTM A182 Grade F3V vs. R30556 Alloy

Both ASTM A182 grade F3V and R30556 alloy are iron alloys. Both are furnished in the annealed condition. They have a modest 34% of their average alloy composition in common, which, by itself, doesn't mean much. There are 31 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 ASTM A182 grade F3V and the bottom bar is R30556 alloy.
