EN 2.4878 Nickel vs. S32950 Stainless Steel

EN 2.4878 nickel belongs to the nickel alloys classification, while S32950 stainless steel belongs to the iron alloys. They have a modest 31% of their average alloy composition in common, which, by itself, doesn't mean much. There are 28 material properties with values for both materials. Properties with values for just one material (6, in this case) are not shown.

For each property being compared, the top bar is EN 2.4878 nickel and the bottom bar is S32950 stainless steel.
