Application Summary AI generated
GB/T 1412-2005 specifies the chemical composition, grade classification, and quality requirements for pig iron used in the production of spheroidal graphite cast iron (ductile iron). It is applied in foundries and metallurgical industries to ensure the raw material meets strict limits on elements like silicon, manganese, phosphorus, and sulfur, enabling consistent nodularization and mechanical properties in castings. This standard is critical for manufacturing ductile iron components such as pipes, automotive parts, and machinery.
