ASTM A414 Steel vs. Ductile Cast Iron
Both ASTM A414 steel and ductile cast iron are iron alloys. There are 30 material properties with values for both materials. Properties with values for just one material (2, in this case) are not shown.
For each property being compared, the top bar is ASTM A414 steel and the bottom bar is ductile cast iron.
