Dec 01, 2009· Table 2 shows a comparison of two sands that have the same AFS-GFN but different distributions. Sand A is a 5-sieve sand because 10% or more of the sample was retained on each of five adjacent sieves (40, 50, 70, 100 and 140). Sand B is a 3-sieve sand because 10% or more was retained on each of only three adjacent sieves (50, 70 and 100).

When a sufficiently hard abrasive particle strikes steel, it deforms the surface into a valley and pushes up peaks. The distance between the top of the peak and the bottom of the valley is known as the depth profile. In the U.S., the depth profile is measured by mils – thouhs of an inch.In the metric system, the micron(one millionth of a meter) is used.
