EN 1.7218 Steel vs. N08120 Nickel

EN 1.7218 steel belongs to the iron alloys classification, while N08120 nickel belongs to the nickel alloys. They have a modest 34% of their average alloy composition in common, which, by itself, doesn't mean much. There are 22 material properties with values for both materials. Properties with values for just one material (10, in this case) are not shown.

For each property being compared, the top bar is EN 1.7218 steel and the bottom bar is N08120 nickel.
