Grade N12MV Nickel vs. EN 1.4547 Stainless Steel

Grade N12MV nickel belongs to the nickel alloys classification, while EN 1.4547 stainless steel belongs to the iron alloys. They have a modest 31% 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 (9, in this case) are not shown.

For each property being compared, the top bar is grade N12MV nickel and the bottom bar is EN 1.4547 stainless steel.
