AISI 304N Stainless Steel vs. Nickel 80A
AISI 304N stainless steel belongs to the iron alloys classification, while nickel 80A belongs to the nickel alloys. They have a modest 31% of their average alloy composition in common, which, by itself, doesn't mean much. There are 30 material properties with values for both materials. Properties with values for just one material (3, in this case) are not shown.
For each property being compared, the top bar is AISI 304N stainless steel and the bottom bar is nickel 80A.
