Grade 200 Maraging Steel vs. Nickel 625

Grade 200 maraging steel belongs to the iron alloys classification, while nickel 625 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 24 material properties with values for both materials. Properties with values for just one material (10, in this case) are not shown.

For each property being compared, the top bar is grade 200 maraging steel and the bottom bar is nickel 625.
