N06650 Nickel vs. SAE-AISI A9 Steel

N06650 nickel belongs to the nickel alloys classification, while SAE-AISI A9 steel belongs to the iron alloys. They have a modest 23% of their average alloy composition in common, which, by itself, doesn't mean much. There are 19 material properties with values for both materials. Properties with values for just one material (12, in this case) are not shown.

For each property being compared, the top bar is N06650 nickel and the bottom bar is SAE-AISI A9 steel.
