ASTM Grade HN Steel vs. CC383H Copper-nickel

ASTM grade HN steel belongs to the iron alloys classification, while CC383H copper-nickel belongs to the copper alloys. They have a modest 27% 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 ASTM grade HN steel and the bottom bar is CC383H copper-nickel.
