EN 1.7231 Steel vs. N06045 Nickel

EN 1.7231 steel belongs to the iron alloys classification, while N06045 nickel belongs to the nickel alloys. They have a modest 25% of their average alloy composition in common, which, by itself, doesn't mean much. There are 25 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 1.7231 steel and the bottom bar is N06045 nickel.
