ASTM A182 Grade F23 vs. EN 1.7390 Steel

Both ASTM A182 grade F23 and EN 1.7390 steel are iron alloys. Both are furnished in the normalized and tempered condition. They have a very high 97% of their average alloy composition in common. There are 33 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 A182 grade F23 and the bottom bar is EN 1.7390 steel.
