In-Spec Low carbon steel shots are produced using selected low carbon, sulphur and phospohorus content scrap. After the melting process, steel shots are produced by melting in the induction furnaces, at about 1600-1650°C, which are automized, followed by quenching process, are crack free with a bainitic microstructure.

Application
The service life of low carbon steel shot has 20% longer life than high carbon steel shot. Low carbon steel shot, with its long life and high hardness, shows excellent performance in removal of sand, scale and rust, deburring, surface preparation and shot peening processes. It is ideal for the use in foundries, forges, ironworks, rolling mills, machine building shops, in steel industry, in automobile and aircraft industries as well as in structural steel industry.
Packing
Steel shots are automatically packed in 25 kg polyethylene bags, 40 bags on 1 tonne EUR wooden pallet and secured with cardboard box and shrink cap.
