ACI-ASTM CC50 Steel vs. N06455 Nickel

ACI-ASTM CC50 steel belongs to the iron alloys classification, while N06455 nickel belongs to the nickel alloys. They have a modest 20% of their average alloy composition in common, which, by itself, doesn't mean much. There are 24 material properties with values for both materials. Properties with values for just one material (11, in this case) are not shown.

For each property being compared, the top bar is ACI-ASTM CC50 steel and the bottom bar is N06455 nickel.
