EN 1.4869 Casting Alloy vs. S41041 Stainless Steel

EN 1.4869 casting alloy belongs to the nickel alloys classification, while S41041 stainless steel belongs to the iron alloys. They have a modest 31% 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 (8, 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 S41041 stainless steel.
