Grade N12MV Nickel vs. S66286 Stainless Steel

Grade N12MV nickel belongs to the nickel alloys classification, while S66286 stainless steel belongs to the iron alloys. They have a modest 34% 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 (7, in this case) are not shown.

For each property being compared, the top bar is grade N12MV nickel and the bottom bar is S66286 stainless steel.
