AISI 304 Stainless Steel vs. N06603 Nickel

AISI 304 stainless steel belongs to the iron alloys classification, while N06603 nickel belongs to the nickel alloys. They have a modest 38% 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 (4, in this case) are not shown.

For each property being compared, the top bar is AISI 304 stainless steel and the bottom bar is N06603 nickel.
