EN 2.4878 Nickel vs. Grade 200 Maraging Steel

EN 2.4878 nickel belongs to the nickel alloys classification, while grade 200 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 24 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 EN 2.4878 nickel and the bottom bar is grade 200 maraging steel.
