EN 1.7779 Steel vs. EN 2.4668 Nickel

EN 1.7779 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 31 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 EN 1.7779 steel and the bottom bar is EN 2.4668 nickel.
