EN 1.7779 Steel vs. Nickel 890
EN 1.7779 steel belongs to the iron alloys classification, while nickel 890 belongs to the nickel alloys. They have a modest 30% 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 (7, in this case) are not shown.
For each property being compared, the top bar is EN 1.7779 steel and the bottom bar is nickel 890.
