EN 2.4951 Nickel vs. S28200 Stainless Steel

EN 2.4951 nickel belongs to the nickel alloys classification, while S28200 stainless steel belongs to the iron alloys. They have a modest 22% of their average alloy composition in common, which, by itself, doesn't mean much. There are 27 material properties with values for both materials. Properties with values for just one material (7, in this case) are not shown.

For each property being compared, the top bar is EN 2.4951 nickel and the bottom bar is S28200 stainless steel.
