EN 2.4668 Nickel vs. EN 1.4057 Stainless Steel

EN 2.4668 nickel belongs to the nickel alloys classification, while EN 1.4057 stainless steel belongs to the iron alloys. They have a modest 36% of their average alloy composition in common, which, by itself, doesn't mean much. There are 31 material properties with values for both materials. Properties with values for just one material (2, in this case) are not shown.

For each property being compared, the top bar is EN 2.4668 nickel and the bottom bar is EN 1.4057 stainless steel.
