Steel Shot for Pre-treatment of surface, steel board, profile steel, steel structure, before painting
Steel Shots are spherical in shape, which are produced by the atomization of molten steel, followed by a series of thermal and mechanical treatments in order to attain martensite microstructure.
Steel shots are widely used as a media for descaling steel components prior to coating. In this application the media is used almost exclusively in centrifugal wheel airless blasting equipment.
They are also used in the foundry casting industry to remove sand from castings after removal from the mould and also for shot peening operations on metal components which are exposed to severe stress in automobile and construction machinery industries.

Typical Applications of Cast Steel Shots
Cast steel shots are widely used in industries. Generally speaking, cast steel shots are widely used for
※ Blast cleaning of casting, forging,sand removal of casting/steel plate/H type steel/steel structure.
※ Rust removal of casting, forging, steel plate, H type steel, steel structure, descaling of forging.
※ Shot peening of gear, heat treatment.
※ Shot blasting of profile steel,ship board,steel board,steel material.
※ Pre-treatment of surface, steel board, profile steel, steel structure, before painting.
