Low Carbon steel shots

Low carbon steel shot is produced using low-carbon scrap, which is well selected and has little sulphur and phosphorus content. In the production process, scrap is melted in induction furnaces at 1600-1650 °C, cooled in water after atomization and have a bainite microstructure. Low carbon steel shot particles are obtained in the form of cracks-free grains. In addition, no heat treatment is applied. Low carbon steel shot has a lower hardness than high carbon steel shot. Because of its microstructure it resist impact well until the moment it suddenly scatters and turns into dust. It is often used for flash descaling. Since low carbon steel shot is softer it not possible to crush it into grit, which is therefore not available. On the other hand, high carbon steel shot have hard, brittle martensitic microstructure since they are made of all kinds of scrap and heat treatment applied after casting causes surface cracks.
