EN 2.4879 Cast Nickel vs. SAE-AISI H12 Steel

EN 2.4879 cast nickel 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 21 material properties with values for both materials. Properties with values for just one material (9, in this case) are not shown.

For each property being compared, the top bar is EN 2.4879 cast nickel and the bottom bar is SAE-AISI H12 steel.
