EN 1.4869 Casting Alloy vs. SAE-AISI H14 Steel

EN 1.4869 casting alloy belongs to the nickel alloys classification, while SAE-AISI H14 steel belongs to the iron alloys. They have a modest 29% of their average alloy composition in common, which, by itself, doesn't mean much. There are 21 material properties with values for both materials. Properties with values for just one material (9, 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 SAE-AISI H14 steel.
