EN 1.7390 Steel vs. N06650 Nickel

EN 1.7390 steel belongs to the iron alloys classification, while N06650 nickel belongs to the nickel alloys. They have a modest 20% of their average alloy composition in common, which, by itself, doesn't mean much. There are 26 material properties with values for both materials. Properties with values for just one material (8, in this case) are not shown.

For each property being compared, the top bar is EN 1.7390 steel and the bottom bar is N06650 nickel.
