ASTM A369 Grade FP91 vs. N06255 Nickel

ASTM A369 grade FP91 belongs to the iron alloys classification, while N06255 nickel belongs to the nickel alloys. They have a modest 26% 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 (6, in this case) are not shown.

For each property being compared, the top bar is ASTM A369 grade FP91 and the bottom bar is N06255 nickel.
