Holmgren, J. J. Choi and P. … WebGrain Size Analysis. Grain size analysis of metal and alloy samples such as aluminum or steel is a very important step in the whole quality control process of metallographic laboratory. The standard grain size is divided into 12 grades, 1-4 grade is coarse grain, 5-8 grade is fine grain, and 9-12 grade is ultra-fine grain size.
