EN 2.4851 Nickel vs. Grade 250 Maraging Steel

EN 2.4851 nickel belongs to the nickel alloys classification, while grade 250 maraging steel belongs to the iron alloys. They have a modest 31% 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 (11, in this case) are not shown.

For each property being compared, the top bar is EN 2.4851 nickel and the bottom bar is grade 250 maraging steel.
