EN 1.0580 Steel vs. Ductile Cast Iron
Both EN 1.0580 steel and ductile cast iron are iron alloys. They have a very high 95% of their average alloy composition in common. 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 EN 1.0580 steel and the bottom bar is ductile cast iron.
