EN 2.4669 Nickel vs. ACI-ASTM CG6MMN Steel

EN 2.4669 nickel belongs to the nickel alloys classification, while ACI-ASTM CG6MMN steel belongs to the iron alloys. They have a modest 36% of their average alloy composition in common, which, by itself, doesn't mean much. There are 25 material properties with values for both materials. Properties with values for just one material (10, in this case) are not shown.

For each property being compared, the top bar is EN 2.4669 nickel and the bottom bar is ACI-ASTM CG6MMN steel.
