SAE-AISI T8 Steel vs. N06002 Nickel

SAE-AISI T8 steel belongs to the iron alloys classification, while N06002 nickel belongs to the nickel alloys. They have a modest 26% 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 (10, in this case) are not shown.

For each property being compared, the top bar is SAE-AISI T8 steel and the bottom bar is N06002 nickel.
