Cement Coating DN80-DN 2600 K9, C40, C30, C25 Ductile Iron Pipe

Definition of Ductile Iron

Ductile iron, also known as nodular iron, is a type of cast iron. During its production, a small amount of magnesium or cerium is added to the molten iron. This addition causes the graphite in the iron to form spherical nodules rather than the flake - like structure found in gray cast iron. This unique microstructure gives ductile iron its excellent mechanical properties, including high strength, good toughness, and remarkable ductility.
 

Product Details

Mechanical Properties

High Tensile Strength: Ductile iron can withstand significant pulling forces. Tensile strength values can range from 400 MPa to over 1000 MPa, depending on the specific grade.

Good Ductility

It can be deformed to a certain extent without breaking. Elongation rates can reach up to 18% or more in some grades, which is far better than many other types of cast iron.

High Impact Resistance

Thanks to its toughness, ductile iron can resist sudden impacts and vibrations well, making it suitable for applications where dynamic loads are present.

Surface Finish

Products made of ductile iron can achieve a relatively smooth surface finish through proper casting and machining processes. This not only improves the aesthetic appearance but also reduces friction when used in fluid - carrying pipelines or mechanical parts.
