ASTM A369 Grade FPA vs. N08024 Nickel

ASTM A369 grade FPA belongs to the iron alloys classification, while N08024 nickel belongs to the nickel alloys. They have a modest 33% 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 (2, in this case) are not shown.

For each property being compared, the top bar is ASTM A369 grade FPA and the bottom bar is N08024 nickel.
