This International Standard specifies a micrographic method of determining the duplex grain size of rolled or forged steel products using standard diagrams or by the point count procedure.
Abstract
Overview
ISO 14250:2000 - Steel - Metallographic characterization of duplex grain size and distributions - defines a micrographic method for identifying and quantifying in rolled or forged steel products. The standard describes how to recognize mixed (duplex) grain-size populations, classify their topology, and estimate area fractions of distinct grain-size constituents using visual comparison charts or statistical point-counting. is intended for metallography and quality control of steel where grain-size heterogeneity affects performance.
