EN 1.6771 Steel vs. N08221 Nickel
EN 1.6771 steel belongs to the iron alloys classification, while N08221 nickel belongs to the nickel alloys. They have a modest 33% 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 (7, in this case) are not shown.
For each property being compared, the top bar is EN 1.6771 steel and the bottom bar is N08221 nickel.
