ACI-ASTM CC50 Steel vs. Nickel 22

ACI-ASTM CC50 steel belongs to the iron alloys classification, while nickel 22 belongs to the nickel alloys. They have a modest 27% 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 (9, in this case) are not shown.

For each property being compared, the top bar is ACI-ASTM CC50 steel and the bottom bar is nickel 22.
