ACI-ASTM CG6MMN Steel vs. EN 2.4951 Nickel

ACI-ASTM CG6MMN steel belongs to the iron alloys classification, while EN 2.4951 nickel belongs to the nickel alloys. They have a modest 36% of their average alloy composition in common, which, by itself, doesn't mean much. There are 26 material properties with values for both materials. Properties with values for just one material (7, in this case) are not shown.

For each property being compared, the top bar is ACI-ASTM CG6MMN steel and the bottom bar is EN 2.4951 nickel.
