S15500 Stainless Steel vs. Nickel 686

S15500 stainless steel belongs to the iron alloys classification, while nickel 686 belongs to the nickel alloys. They have a modest 22% 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 (6, in this case) are not shown.

For each property being compared, the top bar is S15500 stainless steel and the bottom bar is nickel 686.
