ACI-ASTM CA6NM Steel vs. EN 1.4889 Cast Nickel

ACI-ASTM CA6NM steel belongs to the iron alloys classification, while EN 1.4889 cast nickel belongs to the nickel alloys. They have a modest 34% 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 CA6NM steel and the bottom bar is EN 1.4889 cast nickel.
