EN 2.4669 Nickel vs. EN 1.4542 Stainless Steel

EN 2.4669 nickel belongs to the nickel alloys classification, while EN 1.4542 stainless steel belongs to the iron alloys. They have a modest 28% 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 (4, in this case) are not shown.

For each property being compared, the top bar is EN 2.4669 nickel and the bottom bar is EN 1.4542 stainless steel.
