N06025 Nickel vs. ACI-ASTM CF8C Steel

N06025 nickel belongs to the nickel alloys classification, while ACI-ASTM CF8C steel belongs to the iron alloys. They have a modest 40% 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 N06025 nickel and the bottom bar is ACI-ASTM CF8C steel.
