SAE-AISI H25 Steel vs. Nickel 30

SAE-AISI H25 steel belongs to the iron alloys classification, while nickel 30 belongs to the nickel alloys. They have a modest 23% 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 SAE-AISI H25 steel and the bottom bar is nickel 30.
