EN 1.5662 Steel vs. Nickel 718
EN 1.5662 steel belongs to the iron alloys classification, while nickel 718 belongs to the nickel alloys. They have a modest 28% 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 (7, in this case) are not shown.
For each property being compared, the top bar is EN 1.5662 steel and the bottom bar is nickel 718.
