Characteristics of alloy steel grit

　　Alloy steel grit is a high-strength metal abrasive made of scrap steel and wear-resistant materials through casting, crushing, quenching and other processes. It has moderate hardness and excellent toughness, and has the characteristics of strong impact resistance, recyclability, and high cleaning efficiency. This product is widely used in the field of metal surface treatment, covering scenes such as rust removal of castings and strengthening of steel structures. Manufacturers use national standard models (such as G25) to distinguish particle size specifications to meet the needs of different industrial scenarios

　　Production process of alloy steel grit

　　Scrap steel and wear-resistant materials are cast into spheres and then crushed into sharp-edged particles, which are then quenched at high temperature to form the final product. As of 2025, this process can improve the hardness and wear resistance of the material. Early technology used direct quenching and crushing of forged bearing steel

　　Product characteristics of alloy steel sand

　　Hardness range controlled between HRC40-60, taking into account both wear resistance and anti-fragmentation ability

　　Sharp ridged particle structure enhances surface cleaning efficiency and reduces sand consumption

　　Can be recycled 3-5 times, reducing comprehensive use costs

　　Application areas of alloy steel sand

　　Surface treatment: sand cleaning of castings, descaling of forgings, polishing of stainless steel

　　Industrial strengthening: surface strengthening treatment of cast steel parts, forgings, gears and other parts

　　Shipbuilding: pretreatment of hull steel plates and cleaning of welds

　　It needs to be stored in a dry and ventilated environment, and it is forbidden to mix with acidic and alkaline substances to avoid oxidation failure.
