AWS E383 vs. Ductile Cast Iron
Both AWS E383 and ductile cast iron are iron alloys. They have a modest 34% of their average alloy composition in common, which, by itself, doesn't mean much. There are 22 material properties with values for both materials. Properties with values for just one material (10, in this case) are not shown.
For each property being compared, the top bar is AWS E383 and the bottom bar is ductile cast iron.
