ASTM A372 Grade H Steel vs. Nickel 890

ASTM A372 grade H steel belongs to the iron alloys classification, while nickel 890 belongs to the nickel alloys. They have a modest 27% 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 (5, in this case) are not shown.

For each property being compared, the top bar is ASTM A372 grade H steel and the bottom bar is nickel 890.
