GB/T 9441-2009 Metallographic test for spheroidal graphite cast iron
Abstract
This standard specifies the evaluation method of the microstructure of nodular cast iron under an optical microscope.
This standard stipulates the evaluation methods for spheroidization grading, graphite size, number of graphite balls, amount of pearlite, dispersed ferrite, phosphorus eutectic, and carbide, and lists the corresponding grading charts.
This standard is applicable to the evaluation of the metallographic structure of ordinary and low-alloy nodular cast iron in the as-cast, normalized, and annealed states.
