Performance-Based Classification of Inoculants in Ductile Iron Foundries
In ductile iron foundries, inoculation is not just a routine metallurgical step — it is a strategic control point that directly influences casting quality, rejection rates, and profitability. As industries such as automotive, heavy engineering, wind energy, and infrastructure demand stronger and defect-free cast components, foundries can no longer rely on generic inoculant selection. Modern foundries are now shifting toward a performance-based classification of Inoculants — selecting materials based on measurable metallurgical results rather than just chemical composition or cost per ton. This article explores how inoculants are classified by performance in ductile iron foundries, how this approach improves operational efficiency, and what B2B buyers should consider when selecting suppliers. The Role of Inoculants in Ductile Iron Ductile iron, also known as spheroidal graphite (SG) iron, requires careful control of graphite morphology. Unlike grey iron, which forms flake graphite, duc...
