EN 1.7725 Steel vs. N06007 Nickel
EN 1.7725 steel belongs to the iron alloys classification, while N06007 nickel belongs to the nickel alloys. They have a modest 23% of their average alloy composition in common, which, by itself, doesn't mean much. There are 27 material properties with values for both materials. Properties with values for just one material (6, in this case) are not shown.
For each property being compared, the top bar is EN 1.7725 steel and the bottom bar is N06007 nickel.
