Nickel 22 vs. S28200 Stainless Steel

Nickel 22 belongs to the nickel alloys classification, while S28200 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 26 material properties with values for both materials. Properties with values for just one material (8, in this case) are not shown.

For each property being compared, the top bar is nickel 22 and the bottom bar is S28200 stainless steel.
