Nickel 689 vs. S17600 Stainless Steel

Nickel 689 belongs to the nickel alloys classification, while S17600 stainless steel belongs to the iron alloys. They have a modest 28% 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 nickel 689 and the bottom bar is S17600 stainless steel.
