N10665 Nickel vs. EN 1.4986 Stainless Steel

N10665 nickel belongs to the nickel alloys classification, while EN 1.4986 stainless steel belongs to the iron alloys. They have a modest 20% 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 (5, in this case) are not shown.

For each property being compared, the top bar is N10665 nickel and the bottom bar is EN 1.4986 stainless steel.
