ActiveSteel--Determination of area content of graphite-micrographic method using diagrams
钢中石墨碳显微评定方法
Application Summary AI generated
This standard specifies a micrographic method using standard diagrams to determine the area content of graphite in steel. It is applied in metallurgical laboratories and quality control for evaluating the graphite distribution in cast iron and other graphitic steels. The method is used to assess material properties related to wear resistance, machinability, and structural integrity.
