    Microstructure Uniformly deformed pearlite£¨Less impurities£© Tempered martensite + disperse carbide£¨Multiple impurities£©
    density 7.8g/cm3 7.2g/cm3
    hardness 55~58HRC£¨3HRC tolerance£© 40~50HRC£¨10HRCtolerance£©
    Evenness Uniform hardness, size and density Uneven composition and size
    Raw materials High carbon steel wire, dense structure, uniform composition, strong crush resistance Centrifugal casting, many pores, easily broken
    Fatigue life 3500¡«9600 2500
    Consumption rate Consumption is one third of cast steel shot High consumption
    Shot blasting efficiency Can maintain a strong shot (shot) strength in a short time Long shot blasting
    Surface treatment effect The appearance of the workpiece is bright, without scratches, and the surface is not polluted by dust, which is conducive to improving the adhesion of the coating The appearance of the workpiece is dark. The broken pieces easily scratch the surface of the workpiece, and the dust pollution is very heavy, which reduces the coating adhesion.
    environmental impact The amount of dust is very small, which is one-tenth to one-twentieth of the cast steel shot High amount of dust, pollutes the environment
