EN 2.4642 Nickel vs. ACI-ASTM CD3MN Steel

EN 2.4642 nickel belongs to the nickel alloys classification, while ACI-ASTM CD3MN steel belongs to the iron alloys. They have a modest 38% of their average alloy composition in common, which, by itself, doesn't mean much. There are 29 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 2.4642 nickel and the bottom bar is ACI-ASTM CD3MN steel.
