ACI-ASTM CK20 Steel vs. Grade M35-1 Nickel

ACI-ASTM CK20 steel belongs to the iron alloys classification, while grade M35-1 nickel belongs to the nickel alloys. They have a modest 24% 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 (3, in this case) are not shown.

For each property being compared, the top bar is ACI-ASTM CK20 steel and the bottom bar is grade M35-1 nickel.
