N06002 Nickel vs. SAE-AISI M7 Steel

N06002 nickel belongs to the nickel alloys classification, while SAE-AISI M7 steel belongs to the iron alloys. They have a modest 32% 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 N06002 nickel and the bottom bar is SAE-AISI M7 steel.
