EN 1.4596 Stainless Steel vs. Nickel 22

EN 1.4596 stainless steel belongs to the iron alloys classification, while nickel 22 belongs to the nickel alloys. They have a modest 28% of their average alloy composition in common, which, by itself, doesn't mean much. There are 20 material properties with values for both materials. Properties with values for just one material (12, in this case) are not shown.

For each property being compared, the top bar is EN 1.4596 stainless steel and the bottom bar is nickel 22.
