ASTM A369 Grade FP11 vs. ASTM A182 Grade F3V

Both ASTM A369 grade FP11 and ASTM A182 grade F3V are iron alloys. Both are furnished in the annealed condition. They have a very high 97% of their average alloy composition in common. There are 32 material properties with values for both materials. Properties with values for just one material (1, in this case) are not shown.

For each property being compared, the top bar is ASTM A369 grade FP11 and the bottom bar is ASTM A182 grade F3V.
