ACI-ASTM CB30 Steel vs. EN 2.4642 Nickel

ACI-ASTM CB30 steel belongs to the iron alloys classification, while EN 2.4642 nickel belongs to the nickel alloys. They have a modest 30% 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 CB30 steel and the bottom bar is EN 2.4642 nickel.
