ASTM A387 Grade 22L Class 1 vs. ASTM A182 Grade F3V

Both ASTM A387 grade 22L class 1 and ASTM A182 grade F3V are iron alloys. Both are furnished in the annealed condition. They have a very high 99% 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 A387 grade 22L class 1 and the bottom bar is ASTM A182 grade F3V.
