ASTM A182 Grade F122 vs. EN 1.4869 Casting Alloy

ASTM A182 grade F122 belongs to the iron alloys classification, while EN 1.4869 casting alloy belongs to the nickel alloys. They have a modest 31% of their average alloy composition in common, which, by itself, doesn't mean much. There are 27 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 A182 grade F122 and the bottom bar is EN 1.4869 casting alloy.
