EN 1.4874 Stainless Steel vs. Grade N12MV Nickel

EN 1.4874 stainless steel belongs to the iron alloys classification, while grade N12MV nickel belongs to the nickel alloys. They have a modest 29% of their average alloy composition in common, which, by itself, doesn't mean much. There are 25 material properties with values for both materials. Properties with values for just one material (5, in this case) are not shown.

For each property being compared, the top bar is EN 1.4874 stainless steel and the bottom bar is grade N12MV nickel.
