AISI 420 Stainless Steel vs. N06007 Nickel

AISI 420 stainless steel belongs to the iron alloys classification, while N06007 nickel belongs to the nickel alloys. They have a modest 34% 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 420 stainless steel and the bottom bar is N06007 nickel.
