ASTM Grade HN Steel vs. N10629 Nickel
ASTM grade HN steel belongs to the iron alloys classification, while N10629 nickel belongs to the nickel alloys. They have a modest 31% of their average alloy composition in common, which, by itself, doesn't mean much. There are 21 material properties with values for both materials. Properties with values for just one material (11, in this case) are not shown.
For each property being compared, the top bar is ASTM grade HN steel and the bottom bar is N10629 nickel.
