Product Introduction

 

S390, S460 and S550 Low Carbon Steel Shot are large-size steel shot abrasives designed for heavy-duty shot blasting and strong surface cleaning.

These grades provide higher impact force and are suitable for large castings, steel structures, thick steel plates, heavy forgings and workpieces with heavier rust, scale or sand residues.

They are recommended for applications that require faster cleaning speed and stronger surface preparation performance.

Manufacturing Process

 

Low carbon steel shot is produced through melting, atomization, controlled heat treatment, screening and inspection. The process focuses on obtaining a bainite structure, good toughness and stable hardness.

Each batch can be tested for chemical composition, particle size distribution, density, hardness and internal defects. This helps ensure reliable performance in automatic blasting lines and long-cycle abrasive circulation systems.

Advantages

 

  • Large size for strong cleaning power
  • High impact force
  • Efficient removal of rust, scale and sand residues
  • Good durability and service life
  • Stable performance in continuous blasting
  • Helps reduce dust and abrasive breakage
  • Suitable for heavy-duty industrial applications
