Definition - What does Ductile Iron mean?
Ductile iron refers to a type of carbon-iron alloy that is easily molten and cast into any desired shape due to its 2% carbon content. Ductile iron has a higher tendency to develop iron corrosion on its surface but has greater elongation ductility.
Corrosionpedia explains Ductile Iron
Ductile iron has the following key properties compared to other forms of iron:
- Greater yield strength at about 60,000 - 120,000 psi capability
- Greater force resistance
- Reduced material flaking
- Better intergranular boundary forces, therefore less cracking
- Excellent wear resistance due to an elevated graphite concentration
- Greater ability to dissipate heat
- Easily machined
- Combatant against sound vibrations
