Nickel 890 vs. ASTM A387 Grade 2 Steel

Nickel 890 belongs to the nickel alloys classification, while ASTM A387 grade 2 steel belongs to the iron alloys. They have a modest 28% of their average alloy composition in common, which, by itself, doesn't mean much. There are 26 material properties with values for both materials. Properties with values for just one material (6, in this case) are not shown.

For each property being compared, the top bar is nickel 890 and the bottom bar is ASTM A387 grade 2 steel.
