EN 2.4879 Cast Nickel vs. EN 1.4621 Stainless Steel

EN 2.4879 cast nickel belongs to the nickel alloys classification, while EN 1.4621 stainless steel belongs to the iron alloys. They have a modest 37% 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 (5, in this case) are not shown.

For each property being compared, the top bar is EN 2.4879 cast nickel and the bottom bar is EN 1.4621 stainless steel.
