Grade N12MV Nickel vs. Grade 300 Maraging Steel

Grade N12MV nickel belongs to the nickel alloys classification, while grade 300 maraging steel belongs to the iron alloys. They have a modest 29% of their average alloy composition in common, which, by itself, doesn't mean much. There are 22 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 grade 300 maraging steel.
