EN 1.4869 Casting Alloy vs. EN 1.8881 Steel

EN 1.4869 casting alloy belongs to the nickel alloys classification, while EN 1.8881 steel belongs to the iron 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 (6, in this case) are not shown.

For each property being compared, the top bar is EN 1.4869 casting alloy and the bottom bar is EN 1.8881 steel.
