Grade 250 Maraging Steel vs. N07752 Nickel

Grade 250 maraging steel belongs to the iron alloys classification, while N07752 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 (11, in this case) are not shown.

For each property being compared, the top bar is grade 250 maraging steel and the bottom bar is N07752 nickel.
