EN 1.5681 Steel vs. N08120 Nickel

EN 1.5681 steel belongs to the iron alloys classification, while N08120 nickel belongs to the nickel alloys. They have a modest 37% 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 EN 1.5681 steel and the bottom bar is N08120 nickel.
