SAE-AISI H42 Steel vs. Nickel 825

SAE-AISI H42 steel belongs to the iron alloys classification, while nickel 825 belongs to the nickel alloys. They have a modest 38% of their average alloy composition in common, which, by itself, doesn't mean much. There are 22 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 nickel 825.
