ASTM A369 Grade FP9 vs. EN 2.4851 Nickel

ASTM A369 grade FP9 belongs to the iron alloys classification, while EN 2.4851 nickel belongs to the nickel alloys. They have a modest 23% of their average alloy composition in common, which, by itself, doesn't mean much. There are 31 material properties with values for both materials. Properties with values for just one material (1, in this case) are not shown.

For each property being compared, the top bar is ASTM A369 grade FP9 and the bottom bar is EN 2.4851 nickel.
