Excellent toughness. Impact value is comparable to medium carbon steel, over 10 times that of gray iron material.

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

Good plasticity. Elongation ≥7%, similar to high-carbon steel, while grey iron material has zero elongation.

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

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

Ductile iron has comparable strength to cast steel. It boasts a higher yield strength, with a minimum of 40k, whereas cast steel's yield strength is only 36k. In most municipal applications, such as water, saltwater, steam, etc., ductile iron exhibits superior corrosion and oxidation resistance compared to cast steel.
