N08120 Nickel vs. ASTM A387 Grade 2 Steel
N08120 nickel belongs to the nickel alloys classification, while ASTM A387 grade 2 steel belongs to the iron alloys. They have a modest 33% of their average alloy composition in common, which, by itself, doesn't mean much. There are 29 material properties with values for both materials. Properties with values for just one material (3, in this case) are not shown.
For each property being compared, the top bar is N08120 nickel and the bottom bar is ASTM A387 grade 2 steel.
