N06650 Nickel vs. EN 1.4618 Stainless Steel

N06650 nickel belongs to the nickel alloys classification, while EN 1.4618 stainless steel belongs to the iron alloys. They have a modest 37% of their average alloy composition in common, which, by itself, doesn't mean much. There are 26 material properties with values for both materials. Properties with values for just one material (8, in this case) are not shown.

For each property being compared, the top bar is N06650 nickel and the bottom bar is EN 1.4618 stainless steel.
