ACI-ASTM CH20 Steel vs. EN 2.4632 Nickel

ACI-ASTM CH20 steel belongs to the iron alloys classification, while EN 2.4632 nickel belongs to the nickel alloys. They have a modest 35% of their average alloy composition in common, which, by itself, doesn't mean much. There are 29 material properties with values for both materials. Properties with values for just one material (4, in this case) are not shown.

For each property being compared, the top bar is ACI-ASTM CH20 steel and the bottom bar is EN 2.4632 nickel.
