SAE-AISI H12 Steel vs. N06650 Nickel
SAE-AISI H12 steel belongs to the iron alloys classification, while N06650 nickel 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 19 material properties with values for both materials. Properties with values for just one material (12, in this case) are not shown.
For each property being compared, the top bar is SAE-AISI H12 steel and the bottom bar is N06650 nickel.
