ACI-ASTM CC50 Steel vs. EN 2.4951 Nickel

ACI-ASTM CC50 steel belongs to the iron alloys classification, while EN 2.4951 nickel belongs to the nickel alloys. They have a modest 25% 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 (8, in this case) are not shown.

For each property being compared, the top bar is ACI-ASTM CC50 steel and the bottom bar is EN 2.4951 nickel.
