EN 1.4762 Stainless Steel vs. EN 2.4632 Nickel

EN 1.4762 stainless steel belongs to the iron alloys classification, while EN 2.4632 nickel belongs to the nickel alloys. They have a modest 23% 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 1.4762 stainless steel and the bottom bar is EN 2.4632 nickel.
