ACI-ASTM CF10SMnN Steel vs. Nickel 689

ACI-ASTM CF10SMnN steel belongs to the iron alloys classification, while nickel 689 belongs to the nickel alloys. They have a modest 29% of their average alloy composition in common, which, by itself, doesn't mean much. There are 26 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 ACI-ASTM CF10SMnN steel and the bottom bar is nickel 689.
