Grade 250 Maraging Steel vs. N10665 Nickel

Grade 250 maraging steel belongs to the iron alloys classification, while N10665 nickel belongs to the nickel alloys. They have a modest 25% 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 N10665 nickel.
