Nickel 30 vs. SAE-AISI H12 Steel

Nickel 30 belongs to the nickel alloys classification, while SAE-AISI H12 steel belongs to the iron alloys. They have a modest 24% 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 nickel 30 and the bottom bar is SAE-AISI H12 steel.
