Grade 200 Maraging Steel vs. Grade N12MV Nickel

Grade 200 maraging steel belongs to the iron alloys classification, while grade N12MV nickel belongs to the nickel alloys. They have a modest 26% of their average alloy composition in common, which, by itself, doesn't mean much. There are 23 material properties with values for both materials. Properties with values for just one material (6, in this case) are not shown.

For each property being compared, the top bar is grade 200 maraging steel and the bottom bar is grade N12MV nickel.
