SAE-AISI H42 Steel vs. N06975 Nickel

SAE-AISI H42 steel belongs to the iron alloys classification, while N06975 nickel belongs to the nickel alloys. They have a modest 27% 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 SAE-AISI H42 steel and the bottom bar is N06975 nickel.
