ASTM Grade HG10 MNN Steel vs. N10624 Nickel

ASTM grade HG10 MNN steel belongs to the iron alloys classification, while N10624 nickel belongs to the nickel alloys. They have a modest 28% of their average alloy composition in common, which, by itself, doesn't mean much. There are 25 material properties with values for both materials. Properties with values for just one material (9, in this case) are not shown.

For each property being compared, the top bar is ASTM grade HG10 MNN steel and the bottom bar is N10624 nickel.
