EN 1.7367 Steel vs. ACI-ASTM CD3MCuN Steel

Both EN 1.7367 steel and ACI-ASTM CD3MCuN steel are iron alloys. Both are furnished in the normalized and tempered condition. They have 73% of their average alloy composition in common. There are 30 material properties with values for both materials. Properties with values for just one material (3, in this case) are not shown.

For each property being compared, the top bar is EN 1.7367 steel and the bottom bar is ACI-ASTM CD3MCuN steel.
