EN 2.4878 Nickel vs. EN 1.4418 Stainless Steel
EN 2.4878 nickel belongs to the nickel alloys classification, while EN 1.4418 stainless steel belongs to the iron alloys. They have a modest 23% of their average alloy composition in common, which, by itself, doesn't mean much. There are 28 material properties with values for both materials. Properties with values for just one material (5, in this case) are not shown.
For each property being compared, the top bar is EN 2.4878 nickel and the bottom bar is EN 1.4418 stainless steel.
