EN 1.0591 Cast Steel vs. ASTM A182 Grade F5a

Both EN 1.0591 cast steel and ASTM A182 grade F5a are iron alloys. Both are furnished in the normalized and tempered condition. They have a moderately high 94% of their average alloy composition in common. There are 29 material properties with values for both materials. Properties with values for just one material (5, in this case) are not shown.

For each property being compared, the top bar is EN 1.0591 cast steel and the bottom bar is ASTM A182 grade F5a.
