Scope
This document specifies the sampling and sample preparation, evaluation methods, result presentation, and inspection reports for the assessment of carbide spheroidization in steel.
This document is primarily applicable to the evaluation of carbide spheroidization in steel after spheroidizing annealing, where the graph comparison method is suitable for cold heading steel and cold extrusion steel. Other types of steel can be used for reference.
