AISI 303 Stainless Steel vs. N12160 Nickel

AISI 303 stainless steel belongs to the iron alloys classification, while N12160 nickel belongs to the nickel alloys. They have a modest 30% 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 (6, in this case) are not shown.

For each property being compared, the top bar is AISI 303 stainless steel and the bottom bar is N12160 nickel.
