ACI-ASTM CF8C Steel vs. Nickel 690

ACI-ASTM CF8C steel belongs to the iron alloys classification, while nickel 690 belongs to the nickel alloys. They have a modest 40% of their average alloy composition in common, which, by itself, doesn't mean much. There are 30 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 CF8C steel and the bottom bar is nickel 690.
