Nickel 30 vs. SAE-AISI H22 Steel

Nickel 30 belongs to the nickel alloys classification, while SAE-AISI H22 steel belongs to the iron alloys. They have a modest 21% 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 nickel 30 and the bottom bar is SAE-AISI H22 steel.
