Nodular Iron Castings Parts

Unlike traditional gray cast iron, the graphite of ductile iron is distributed in a spherical shape, which makes ductile iron have better mechanical properties, especially tensile strength, ductility and impact resistance. Ductile iron has become a cast iron material widely used in various industrial fields, and is widely used in automobiles, machinery, pipelines, construction, mining and other industries.

Performance characteristics of ductile iron

Ductile iron has the advantages of gray cast iron, while overcoming the brittleness of gray cast iron, and has the following excellent properties:

Excellent mechanical properties: The tensile strength, yield strength and elongation of ductile iron are much higher than those of traditional gray cast iron, and it has good toughness and impact resistance. Its tensile strength can generally reach 300-1000 MPa, which is much higher than ordinary gray cast iron.

Good castability: Nodular Iron Castings Parts has good fluidity and filling capacity during the casting process, and can be cast into castings with complex shapes and fine wall thickness. At the same time, the casting cost of ductile iron is relatively low, which is suitable for large-scale production.

Good wear resistance: Due to the spherical distribution of graphite, ductile iron shows good wear resistance when subjected to friction and wear, and is widely used in parts in high wear environments such as gears, bearings, and pump bodies.

Combination of high strength and high toughness: Ductile iron has balanced strength and toughness, and can withstand large loads without breaking easily. It can show good plastic deformation ability under extreme loads, especially suitable for mechanical equipment parts that are subjected to impact and vibration.

Corrosion resistance: Ductile iron has good corrosion resistance in certain environments, especially in certain weakly acidic or weakly alkaline media. It can adapt to harsh environmental conditions better than gray cast iron.
