Nickel 693 vs. ASTM F15 Fe-Ni-Co

Nickel 693 belongs to the nickel alloys classification, while ASTM F15 Fe-Ni-Co belongs to the iron alloys. They have a modest 34% of their average alloy composition in common, which, by itself, doesn't mean much. There are 21 material properties with values for both materials. Properties with values for just one material (10, in this case) are not shown.

For each property being compared, the top bar is nickel 693 and the bottom bar is ASTM F15 Fe-Ni-Co.
