EN 1.8201 Steel vs. ACI-ASTM CE8MN Steel

Both EN 1.8201 steel and ACI-ASTM CE8MN steel are iron alloys. Both are furnished in the normalized and tempered condition. They have 64% of their average alloy composition in common. There are 30 material properties with values for both materials. Properties with values for just one material (4, in this case) are not shown.

For each property being compared, the top bar is EN 1.8201 steel and the bottom bar is ACI-ASTM CE8MN steel.
