Nickel 718 vs. EN 1.5662 Steel
Nickel 718 belongs to the nickel alloys classification, while EN 1.5662 steel belongs to the iron 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 nickel 718 and the bottom bar is EN 1.5662 steel.
