R30556 Alloy vs. EN 1.0420 Cast Steel

Both R30556 alloy and EN 1.0420 cast steel are iron alloys. They have a modest 29% of their average alloy composition in common, which, by itself, doesn't mean much. There are 29 material properties with values for both materials. Properties with values for just one material (4, in this case) are not shown.

For each property being compared, the top bar is R30556 alloy and the bottom bar is EN 1.0420 cast steel.
