EN 2.4851 Nickel vs. ACI-ASTM CB30 Steel

EN 2.4851 nickel belongs to the nickel alloys classification, while ACI-ASTM CB30 steel belongs to the iron alloys. They have a modest 34% of their average alloy composition in common, which, by itself, doesn't mean much. There are 27 material properties with values for both materials. Properties with values for just one material (6, in this case) are not shown.

For each property being compared, the top bar is EN 2.4851 nickel and the bottom bar is ACI-ASTM CB30 steel.
