N10665 Nickel vs. ACI-ASTM CT15C Steel

N10665 nickel belongs to the nickel alloys classification, while ACI-ASTM CT15C steel belongs to the iron 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 (5, in this case) are not shown.

For each property being compared, the top bar is N10665 nickel and the bottom bar is ACI-ASTM CT15C steel.
