The applications of different steel grit hardness

1. GP steel grit : When the new abrasive is made, it is sharp-edged. The corners are quickly rounded during use, which is especially suitable for the surface pretreatment of steel.

2. GL steel grit : Although the hardness of such steel sand is higher than that of GP steel sand, it still loses the angularity during the sand blasting process, and is especially suitable for the steel surface pretreatment of steel surface.

3. GH steel grit : This type of steel sand has a high hardness and will always maintain an angular shape during sandblasting operations, which is particularly effective for forming regular, hairy surfaces. When GH steel grit is used in shot blasting operations, consideration should be given to applications where construction requirements take precedence over price factors (eg, roll treatment in cold rolling mills). This steel grit is mainly used in compressed air shot peening equipment.
