ASTM A387 Grade 22 Steel vs. EN 2.4668 Nickel

ASTM A387 grade 22 steel belongs to the iron alloys classification, while EN 2.4668 nickel belongs to the nickel alloys. They have a modest 22% 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 A387 grade 22 steel and the bottom bar is EN 2.4668 nickel.
