SAE-AISI 1144 Steel vs. N08024 Nickel

SAE-AISI 1144 steel belongs to the iron alloys classification, while N08024 nickel belongs to the nickel alloys. They have a modest 33% of their average alloy composition in common, which, by itself, doesn't mean much. There are 30 material properties with values for both materials. Properties with values for just one material (3, in this case) are not shown.

For each property being compared, the top bar is SAE-AISI 1144 steel and the bottom bar is N08024 nickel.
