EN 2.4680 Cast Nickel vs. S44735 Stainless Steel

EN 2.4680 cast nickel belongs to the nickel alloys classification, while S44735 stainless steel belongs to the iron alloys. They have a modest 32% of their average alloy composition in common, which, by itself, doesn't mean much. There are 25 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 2.4680 cast nickel and the bottom bar is S44735 stainless steel.
