Key Metallurgical Methods for Producing High-Quality S.G. Iron
A Foundry-Focused Guide by Bansal Brothers Spheroidal Graphite (S.G.) iron, also known as ductile iron, has become a backbone material for industries that demand strength, durability, and reliability. From automotive and tractor components to pipes, pumps, valves, and heavy engineering castings, S.G. iron is preferred for its superior mechanical performance compared to grey iron. However, producing high-quality S.G. iron consistently requires more than basic melting and pouring. It demands precise metallurgical control, the right treatment method, and reliable nodulizing materials such as ferro silicon magnesium. At Bansal Brothers, a trusted supplier of ferro alloys for the Indian and global foundry industry, we work closely with foundries to help them adopt the Best Methods To Make S G Iron with high recovery, stable nodularity, and reduced rejections. This article explains the key metallurgical methods that directly influence S.G. iron quality from a practical B2B perspective. Unde...
