Grade N12MV Nickel vs. EN 1.4945 Stainless Steel

Grade N12MV nickel belongs to the nickel alloys classification, while EN 1.4945 stainless steel belongs to the iron alloys. They have a modest 23% 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 (8, in this case) are not shown.

For each property being compared, the top bar is grade N12MV nickel and the bottom bar is EN 1.4945 stainless steel.
