EN 1.6958 Steel vs. EN 2.4879 Cast Nickel
EN 1.6958 steel belongs to the iron alloys classification, while EN 2.4879 cast nickel belongs to the nickel alloys. They have a modest 21% 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 (7, in this case) are not shown.
For each property being compared, the top bar is EN 1.6958 steel and the bottom bar is EN 2.4879 cast nickel.
