EN 2.4952 Nickel vs. S32950 Stainless Steel

EN 2.4952 nickel belongs to the nickel alloys classification, while S32950 stainless steel belongs to the iron alloys. They have a modest 25% 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 (6, in this case) are not shown.

For each property being compared, the top bar is EN 2.4952 nickel and the bottom bar is S32950 stainless steel.
