N06219 Nickel vs. AISI 446 Stainless Steel

N06219 nickel belongs to the nickel alloys classification, while AISI 446 stainless 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 30 material properties with values for both materials. Properties with values for just one material (6, in this case) are not shown.

For each property being compared, the top bar is N06219 nickel and the bottom bar is AISI 446 stainless steel.
