Advantages of Low-Carbon Steel Shot

• Long durability. Low-carbon steel shot has the longest life span among all cast steel abrasives.
• High impact resistance. The fully controlled casting and heat treatment processes create the toughest and most impact-resistant tempered bainite microstructure.
• Low dust emission. Low-carbon steel shots become smaller when being blasted and do not fracture at once, so the dust generation is greatly reduced.
• Good cleaning efficiency. Low carbon steel shot is not easy to break due to its structure and high toughness, and the number of repeated cycles reaches about 3600 times. It is especially suitable to be used as blasting media for auto-blasting machines.
• Lower operating cost. Low-carbon steel shot becomes smaller as it wears, and it rarely fractures into small pieces as the high-carbon steel shot does. This feature causes less wear in the lining of auto blast machines and wheel blades, thus reducing the cost of operation and increasing the service life of the blasting equipment.

Production of Low-Carbon Steel Shot

Low-carbon cast steel shot is produced from high-quality materials with low content of carbon (C), phosphorus (P) and sulfur (S) and pure, precisely dosed alloying elements.

In the production process, scrap is melted in induction furnaces at 1600-1650 °C, cooled in water after atomization, and has a bainite microstructure.
