Nickel 30 vs. ASTM A369 Grade FP9

Nickel 30 belongs to the nickel alloys classification, while ASTM A369 grade FP9 belongs to the iron alloys. They have a modest 25% 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 nickel 30 and the bottom bar is ASTM A369 grade FP9.
