EN 1.6982 Stainless Steel vs. EN 2.4851 Nickel

EN 1.6982 stainless steel belongs to the iron alloys classification, while EN 2.4851 nickel belongs to the nickel alloys. They have a modest 31% of their average alloy composition in common, which, by itself, doesn't mean much. There are 29 material properties with values for both materials. Properties with values for just one material (5, in this case) are not shown.

For each property being compared, the top bar is EN 1.6982 stainless steel and the bottom bar is EN 2.4851 nickel.
