N12160 Nickel vs. AISI 321H Stainless Steel

N12160 nickel belongs to the nickel alloys classification, while AISI 321H stainless steel belongs to the iron alloys. They have a modest 32% of their average alloy composition in common, which, by itself, doesn't mean much. There are 28 material properties with values for both materials. Properties with values for just one material (7, in this case) are not shown.

For each property being compared, the top bar is N12160 nickel and the bottom bar is AISI 321H stainless steel.
