N06650 Nickel vs. SAE-AISI M44 Steel

N06650 nickel belongs to the nickel alloys classification, while SAE-AISI M44 steel belongs to the iron alloys. They have a modest 28% 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 (10, in this case) are not shown.

For each property being compared, the top bar is N06650 nickel and the bottom bar is SAE-AISI M44 steel.
