ASTM A182 Grade F12 Class 2 vs. EN 2.4665 Nickel

ASTM A182 grade F12 class 2 belongs to the iron alloys classification, while EN 2.4665 nickel belongs to the nickel alloys. They have a modest 21% 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 (3, in this case) are not shown.

For each property being compared, the top bar is ASTM A182 grade F12 class 2 and the bottom bar is EN 2.4665 nickel.
