Nickel 80A vs. S45500 Stainless Steel

Nickel 80A belongs to the nickel alloys classification, while S45500 stainless steel belongs to the iron alloys. They have a modest 23% of their average alloy composition in common, which, by itself, doesn't mean much. There are 25 material properties with values for both materials. Properties with values for just one material (10, in this case) are not shown.

For each property being compared, the top bar is nickel 80A and the bottom bar is S45500 stainless steel.
