The steel grit is granule shape made from the crushed high carbon cast steel, divided into three hardness (LSGH,LSGL,LSGP)to meet different requirements. The processed sand is separated into ten classes of SAE standard for sandblasting application.
Products of different sizes and harness are used according to different circumstances, like stick cylinder engraving and granite cutting, etc.
Our steel sand adopts the production process of Japan New East, the hardness, density and micro-structure of products are consistent and homogeneous, and meanwhile have good strength and durability. These features have good shot blasting cleaning function.
Steel sand is widely used in the pretreatment of steel work piece coating, the most applied way in this process is sandblasting booth with recycling device. The angular sand and related hardness will make the cleaning speed fast and can recycle effectively.
Steel sand is widely used in the sand cleaning of castings, the work piece will have casting sand adsorbed onto the castings in excessive high temperature, out of the range of steel shot cleaning capacity, at this time, steel sands can only be used.
When the shot blasting equipment that using steel shots can’t clean the steel work piece effectively, steel sand can be used.
Industry application
Aviation, automobile industry, sandblasting/paint spraying manufacturer; consumable manufacturing, container manufacturing/ repairing, casting
Granite / stone cutting, ship building and repairing, petroleum and gas pipeline, workshop maintaining and metal processing.
Process application range
Surface pretreatment of coating, casting sand-cleaning, pipeline descaling, etc.
Instruction and performance
Instruction and performance
When used to clean and remove the rust and oxide layer, the effect will be best using the centrifuge shot blasting equipment.

LSSG steel sand: the hardness of this kind of steel sand is higher than GP steel sand, but in the sandblasting process, edges will be lost. It applies to the oxide layer removing and pretreatment of steel surface.
LSGH steel sand: the hardness of this kind of steel sand is high, edges will be kept in the re-sandblasting process, especially effective to the regular fluffing surface. GH steel sand when used in the shot peening, should be considered of the occasion that construction requirement is prior to price factors (like roll processing of cold rolling plant). This kind of steel shot is mainly used in compressed air shot peening equipment.
