Good resilience. Impact value is similar to medium carbon steel, over 10 times that of gray iron material.

High corrosion resistance. The water spray corrosion test shows that the corrosion amount after 90 days is only 1/40 of steel pipes and 1/10 of gray iron pipes. The service life is twice that of gray iron pipes and five times that of ordinary steel pipes.

Good ductility. Elongation ≥ 7%, comparable to high-carbon steel, while gray cast iron has zero elongation.

High strength. Tensile strength ób≥420MPa, yield strength ós≥300MPa, equivalent to low-carbon steel, three times that of gray iron material.

Due to the spheroidal graphite microstructure of ductile iron, it is superior to cast steel in reducing vibration, thus more conducive to stress reduction. One significant reason for choosing ductile iron is its lower cost compared to cast steel. The low cost of ductile iron makes it more popular, improves casting efficiency, and also reduces machining costs for ductile iron.

Graphite cast iron has comparable strength to cast steel, with a higher yield strength, starting at 40k, compared to the 36k of cast steel. In most municipal applications, such as water, saltwater, steam, etc., the corrosion and oxidation resistance of graphite cast iron exceeds that of cast steel.
