25-06-2019· The hot-rolled material, by the very nature of its processing, has hard and soft spots, residual stresses, voids, and other material deficiencies, making it more difficult to machine. The problem with some high strength steels is the hardest part is only the outside layers, so when the shaft is machined down you will lose the strength.

For sand, a distinction is made between 3 particle size ranges. Fine sand has grain sizes of > 0.063 – 0.2 mm, while medium sand is defined as > 0.2 – 0.63 mm and coarse sand as > 0.63 – 2.0 mm. Smaller grain sizes below fine sand are referred to as silt, even smaller sizes below 0.002 mm as clay.
