WebApr 15, 2024 · What Rates Grain Size? Grain size is often referenced as a unitless number, between about 5 and 15. This is a relative scale, related to average grain diameter. The higher the number, the finer the grain size. The methodology for measuring and rating grain size is outlined in ASTM E112. It involves counting the number of grains in a given area. Web(b) This portion of the problem calls for us to estimate the ASTM grain size number for this same material. The average grain size number, n, is related to the number of grains per square inch, N, at a magnification of 100 × according to Equation 4.16. Inasmuch as the magnification is 100 ×, the value of N is measured directly from the
