EN 2.4663 Nickel vs. S21900 Stainless Steel

EN 2.4663 nickel belongs to the nickel alloys classification, while S21900 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 2.4663 nickel and the bottom bar is S21900 stainless steel.
