EN 2.4680 Cast Nickel vs. EN 1.4749 Stainless Steel

EN 2.4680 cast nickel belongs to the nickel alloys classification, while EN 1.4749 stainless steel belongs to the iron alloys. They have a modest 29% 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 2.4680 cast nickel and the bottom bar is EN 1.4749 stainless steel.
