SAE-AISI P4 Steel vs. N06920 Nickel
SAE-AISI P4 steel belongs to the iron alloys classification, while N06920 nickel belongs to the nickel alloys. They have a modest 25% of their average alloy composition in common, which, by itself, doesn't mean much. There are 23 material properties with values for both materials. Properties with values for just one material (8, in this case) are not shown.
For each property being compared, the top bar is SAE-AISI P4 steel and the bottom bar is N06920 nickel.
