N10003 Nickel vs. ACI-ASTM CN7MS Steel

N10003 nickel belongs to the nickel alloys classification, while ACI-ASTM CN7MS steel belongs to the iron alloys. They have a modest 37% of their average alloy composition in common, which, by itself, doesn't mean much. There are 27 material properties with values for both materials. Properties with values for just one material (6, in this case) are not shown.

For each property being compared, the top bar is N10003 nickel and the bottom bar is ACI-ASTM CN7MS steel.
