EN 1.4869 Casting Alloy vs. EN 1.7366 Steel

EN 1.4869 casting alloy belongs to the nickel alloys classification, while EN 1.7366 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 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 1.7366 steel.
