Abstract

PURPOSE:To provide a non-destructive method of measuring the crystal grain of a cold rolled stainless plate or strip which is in an annealing step in which the preparation of a speciment for the grain size measurement and its measuring step are eliminated whereby the step sequence is smoothened.
