ACI-ASTM CF16Fa Steel vs. N12160 Nickel

ACI-ASTM CF16Fa steel belongs to the iron alloys classification, while N12160 nickel belongs to the nickel alloys. They have a modest 34% 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 ACI-ASTM CF16Fa steel and the bottom bar is N12160 nickel.
