This document specifies procedures for quantitative analysis of Mn dendritic segregation in steel billets using electron probe microanalysis (EPMA).

This document is mainly applied in continuously cast product with Mn content more than 0.01 % by mass. This method can also be used in steel ingots and steel products.

The minimum size of analysable dendrites is totally dependent on the resolution of microscope of EPMA and beam size of filament used for quantitative analysis.
