Grade CX2M Nickel vs. Grade 350 Maraging Steel

Grade CX2M nickel belongs to the nickel alloys classification, while grade 350 maraging steel belongs to the iron alloys. They have a modest 24% 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 (9, in this case) are not shown.

For each property being compared, the top bar is grade CX2M nickel and the bottom bar is grade 350 maraging steel.
