EN 2.4856 Nickel vs. ACI-ASTM CB7Cu-2 Steel

EN 2.4856 nickel belongs to the nickel alloys classification, while ACI-ASTM CB7Cu-2 steel belongs to the iron alloys. They have a modest 23% 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 2.4856 nickel and the bottom bar is ACI-ASTM CB7Cu-2 steel.
