ASTM A216 Cast Steel vs. Ductile Cast Iron
Both ASTM A216 cast steel and ductile cast iron are iron alloys. There are 28 material properties with values for both materials. Properties with values for just one material (5, in this case) are not shown.
For each property being compared, the top bar is ASTM A216 cast steel and the bottom bar is ductile cast iron.
