Cast Steel Grits market are divided into primary quenching and secondary quenching

  At present, the Cast Steel Grits market are divided into primary quenching and secondary quenching, which are difficult to distinguish from the composition, hardness, and metallographic structure, but the secondary quenched steel pellets have coarse grains and low fatigue life. Primary quenched Cast Steel Grits, because there is no reheating, quenching process, and then formed on the surface of thin oxide film of iron oxide is relatively thin. So it looks very bright; Well after the second quenching, due to a quenching treatment, and after a heat quenching process, the surface of the iron oxide film becomes thick, non-reflective, looks not shiny. Therefore, the appearance of Engineering Machinery Cast Steel Grits is not as bright as possible, but should pay attention to whether or not the secondary quenching heat treatment.

  In order to prevent steel corrosion, the most common method is to use a coating to protect the surface of steel components. Before the coating is protected, the surface of the steel component must be cleaned. Thousands of products and industries such as the shipbuilding industry, storage tanks, bridges, steel structures, power stations, automobiles, locomotives, military equipment, and aerospace equipment must be surface-treated prior to painting. Metal abrasives are effective cleaning media.
