Grade 200 Maraging Steel vs. EN 2.4878 Nickel
Grade 200 maraging steel belongs to the iron alloys classification, while EN 2.4878 nickel belongs to the nickel alloys. They have a modest 29% 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 (7, in this case) are not shown.
For each property being compared, the top bar is grade 200 maraging steel and the bottom bar is EN 2.4878 nickel.
