SAE-AISI 1021 Steel vs. N06045 Nickel

SAE-AISI 1021 steel belongs to the iron alloys classification, while N06045 nickel belongs to the nickel alloys. They have a modest 24% 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 (7, in this case) are not shown.

For each property being compared, the top bar is SAE-AISI 1021 steel and the bottom bar is N06045 nickel.
