EN 1.4031 Stainless Steel vs. EN 2.4816 Nickel

EN 1.4031 stainless steel belongs to the iron alloys classification, while EN 2.4816 nickel belongs to the nickel alloys. They have a modest 22% 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 1.4031 stainless steel and the bottom bar is EN 2.4816 nickel.
