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, the depth profile is measured by mils – thouhs of an the metric system, the micron(one millionth of a meter) is used.
AFSFIRST What is Foundry Sand? • Foundry sand is a highquality uniform silica sand that is used to make molds and cores for ferrous and nonferrous metal castings. • Foundry sands typically comprise of >80% highquality silica sand, 510% bentoniteclay, 2 to 5% water and less than 5% sea coal.
