ASTM grain size number(n) is related with the number of grains that you can count in 100X magnification (N) by the relation, N=2 (n-1). So ASTM grain size number increases with decreasing grain size.Grain size per ASTM - "Austenitic grain size of 5 or finer , astm 588 grain sizeMar 28, 2008 · I am new to the steel industry and I have run across a requirement for "Austenitic grain size of 5 or finer". I have run across a few references to ASTM E 112 as a guide but my question is: is a grade of 5-B finer than a 5?Solved: Determine, By Counting, The ASTM Grain Size Of The , astm 588 grain sizeDetermine, by counting, the ASTM grain size of the low carbon sheet steel shown in Figure. This micrograph is at 100x. Classify the grain size according to the value of n and determine it it is coarse, medium, fine, or ultrafine grain size.Some results are removed in response to a notice of local law requirement.

The conventional material has a larger average grain size than the fine + ALA material but has nearly the same largest grain size. The difference in largest grain size is less than 1 ASTM grain size between the two variants.
5.2 These test methods may be applied to specimens or products containing randomly intermingled grains of two or more significantly different sizes (henceforth referred to as random duplex grain size). Examples of random duplex grain sizes include: isolated coarse grains in a matrix of much finer grains, extremely wide distributions of grain sizes, and bimodal distributions of grain size.Some results are removed in response to a notice of local law requirement.
