Grade 350 Maraging Steel vs. N10629 Nickel

Grade 350 maraging steel belongs to the iron alloys classification, while N10629 nickel belongs to the nickel alloys. They have a modest 28% 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 (7, in this case) are not shown.

For each property being compared, the top bar is grade 350 maraging steel and the bottom bar is N10629 nickel.
