Application Summary AI generated
GB/T 5612-2008 specifies the coding system for representing cast iron grades, including the use of letters and numbers to denote material type, mechanical properties, and composition. It is applied in the metallurgy and manufacturing industries for labeling cast iron products such as gray iron, ductile iron, and malleable iron in engineering drawings, procurement specifications, and quality testing. This standard ensures consistent identification and classification of cast iron materials across production, supply, and inspection processes in China.
