EN 1.6579 Steel vs. EN 1.4869 Casting Alloy
EN 1.6579 steel belongs to the iron alloys classification, while EN 1.4869 casting alloy belongs to the nickel alloys. They have a modest 22% 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 1.6579 steel and the bottom bar is EN 1.4869 casting alloy.
