N06985 Nickel vs. EN 1.4122 Stainless Steel

N06985 nickel belongs to the nickel alloys classification, while EN 1.4122 stainless steel belongs to the iron alloys. They have a modest 39% of their average alloy composition in common, which, by itself, doesn't mean much. There are 30 material properties with values for both materials. Properties with values for just one material (2, in this case) are not shown.

For each property being compared, the top bar is N06985 nickel and the bottom bar is EN 1.4122 stainless steel.
