Advantages and disadvantages of lower-hardness steel shot

The advantages of lower-hardness steel shot include:

Long service life: Lower-hardness steel shot experiences less wear during use and is resistant to deformation or breakage, resulting in a long service life.

Minimal surface scratching: Lower-hardness steel shot is less likely to leave scratches upon impact with the workpiece surface. It preserves the smoothness of the workpiece surface and is suitable for cleaning small precision parts, aluminum alloy products, etc.

Relatively smooth cleaned surface: The workpiece surface remains relatively smooth after cleaning with lower-hardness steel shot, making it suitable for workpieces with strict surface finish requirements.

The disadvantages of lower-hardness steel shot include:

Low cleaning intensity: The impact force of lower-hardness steel shot is weak, resulting in relatively low cleaning intensity; achieving the same cleaning effect requires more time.

Low cleaning efficiency: Due to the weaker impact, cleaning efficiency is lower, and completing the cleaning task may take longer.

Unsuitable for heavily rusted workpieces or those with thick oxide scale: For workpieces that are heavily rusted or have thick oxide scale, lower-hardness steel shot cannot deeply clean small pores and grooves, which affects cleaning quality.
