Steel grit with different hardness
Steel grit is a sharp-edged abrasive when it is newly made. The edges and corners are quickly rounded during use. It is especially suitable for pre-treatment of oxide scale removal on steel surfaces. Operation.
Steel Grit Although the hardness of this type of steel grit is higher than that of steel grit, it will still lose its edges and corners during the sandblasting process. It is especially suitable for pre-treatment operations of removing oxide scale from the surface of steel.
Steel grit: This type of steel grit has a very high hardness and will always maintain edges and corners during sandblasting operations. It is particularly effective in forming regular, hairy surfaces. When steel grit is used for shot peening machine operations, occasions where construction requirements take precedence over price factors (such as roll treatment in cold rolling mills) should be considered. This steel grit is mainly used in compressed air shot peening equipment.
