S32550 Stainless Steel vs. Nickel 59

S32550 stainless steel belongs to the iron alloys classification, while nickel 59 belongs to the nickel alloys. They have a modest 33% 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 (7, in this case) are not shown.

For each property being compared, the top bar is S32550 stainless steel and the bottom bar is nickel 59.
