EN 1.8818 Steel vs. N08026 Nickel

EN 1.8818 steel belongs to the iron alloys classification, while N08026 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 30 material properties with values for both materials. Properties with values for just one material (3, in this case) are not shown.

For each property being compared, the top bar is EN 1.8818 steel and the bottom bar is N08026 nickel.
