N06250 Nickel vs. SAE-AISI A3 Steel

N06250 nickel belongs to the nickel alloys classification, while SAE-AISI A3 steel belongs to the iron alloys. They have a modest 21% 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 N06250 nickel and the bottom bar is SAE-AISI A3 steel.
