ASTM F15 Fe-Ni-Co vs. Monel 400

ASTM F15 Fe-Ni-Co belongs to the iron alloys classification, while Monel 400 belongs to the nickel alloys. They have a modest 31% of their average alloy composition in common, which, by itself, doesn't mean much. There are 24 material properties with values for both materials. Properties with values for just one material (8, in this case) are not shown.

For each property being compared, the top bar is ASTM F15 Fe-Ni-Co and the bottom bar is Monel 400.
