Nickel 625 vs. Grade 300 Maraging Steel
Nickel 625 belongs to the nickel alloys classification, while grade 300 maraging steel belongs to the iron alloys. They have a modest 27% 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 nickel 625 and the bottom bar is grade 300 maraging steel.
