High Carbon Steel Grit

STEEL GRIT (G) – it can be supplied in three different hardness grades: GH, GM, and GN.The angular nature of steel grit produces an etched surface on metal.

G abrasives marked GH possess a minimum hardness of 60 HRC. We recommend them exclusively for blasting with compressed air. Due to their exceptional abrasive characteristics, optimal surface profiles can be achieved and this is a basic requirement for high-quality surface protection. Exceptionally GH abrasives can be used in wheel blasting machines for the blasting of cylinders.

Characteristics: In the process of blasting GH abrasives keep their original sharp-edged form. G abrasives marked GM possess a hardness from 52 to 56 HRc. They are recommended for the preparation of surfaces with high requirements concerning the purification and roughness profile (enameling, metal coating.

In the process of blasting, GM abrasives lose their original sharp-edged form. G abrasives marked GN possess a hardness from 48 to 52 HRC. They are recommended for the applications in the surface preparation (cleaning) prior to painting, for the removal of sand.

Features

Steel sand features: moderate hardness, strong toughness, impact resistance, can be used repeatedly for several times, long life, good rebound, strong adhesion, fast cleaning speed, low sand consumption, no breakage, high brightness of the cleaned workpiece, good technical effect.

Steel grit of different hardness:

GP steel grit: When this abrasive is newly made, it is sharp-edged. The edges and corners are quickly rounded during use, which is particularly suitable for pretreatment of steel surface descaling.

GL steel grit: Although this type of steel grit is harder than GP steel grit, it will still lose its edges and corners during the sandblasting process, which is particularly suitable for pretreatment of steel surface descaling.

GH steel grit: This type of steel grit has a very high hardness and will always maintain its edges and corners during sandblasting. It is particularly effective for forming regular, hairy surfaces. When GH steel grit is used in shot blasting machine operations, it should be considered in situations where construction requirements take precedence over price factors (such as roller processing in cold rolling mills). This steel grit is mainly used in compressed air shot blasting.
