Ductile iron, a material known as the “invisible steel artery” due to its combination of the strength of steel and the toughness of iron, will be explored in this article. This article will delve into the unique manufacturing process of ductile iron, analyze its core applications, and introduce how DINSEN, a ductile iron pipe manufacturer, meets global infrastructure needs with high-quality products.
Traditional gray cast iron is brittle and prone to fracture due to the flake-like structure of carbon. The advent of ductile iron has completely changed this. It involves adding a suitable spheroidizing agent (such as rare-earth magnesium alloy) to molten iron, causing carbon to crystallize into spherical graphite through a spheroidization reaction. This change in microstructure eliminates the cutting effect of flake graphite on the metal matrix. Subsequent addition of an inoculant refines the grain size, further enhancing its mechanical properties, making it an ideal material for manufacturing the city’s “lifeline”—water supply pipes.
Main Applications of Ductile Iron Pipes:
1. Urban water supply systems
2. Sewage and stormwater drainage projects
3. Gas transmission
