EN 1.4912 Stainless Steel vs. N12160 Nickel

EN 1.4912 stainless steel belongs to the iron alloys classification, while N12160 nickel belongs to the nickel alloys. They have a modest 32% 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 (6, in this case) are not shown.

For each property being compared, the top bar is EN 1.4912 stainless steel and the bottom bar is N12160 nickel.
