What is GL Steel Girt ?

GL Steel Grit

GL Steel Grit is a type of cast steel abrasive that has been quenched and tempered to achieve a balance of hardness and durability, making it suitable for a variety of industrial surface treatment applications.

Characteristics

1.Hardness: GL steel grit has a hardness range of 54-61 HRC (Rockwell Hardness), placing it in the medium-hardness category according to SAE standards.

2.Shape: While GL steel grit is harder than GP steel grit, its edges and corners tend to become more rounded during the blasting process. This makes it ideal for applications where a certain level of hardness is required but without causing excessive surface damage.

3.Chemical Composition: It contains carbon (C) at 0.80%-1.20%, manganese (Mn) at 0.35%-1.20%, silicon (Si) at 0.40%-1.50%, with sulfur (S) and phosphorus (P) content not exceeding 0.05% each.

4.Density: The density of GL steel grit is approximately 7.4 g/cm3.

5.Microstructure: It features a uniform structure of tempered martensite and bainite.

Applications

GL steel grit is suitable for various industrial scenarios, including:

1.Rust and Paint Removal: Quickly removes rust and old paint from metal surfaces.

Descaling: Effective in removing scale from steel surfaces, particularly for medium-hardness surface treatments.

2.Surface Preparation: Provides the ideal surface roughness for metal coating or painting.

3.Blast Cleaning: Suitable for medium-duty blast cleaning tasks.

Advantages

1.Efficient Cleaning: The hardness of GL steel grit enables it to effectively remove contaminants from metal surfaces.

2.Durability: Quenched and tempered to enhance wear resistance, GL steel grit has a long service life.

3.Versatility: Suitable for a wide range of metal surface treatment tasks, meeting various industrial needs.

Suitable Equipment

GL steel grit is recommended for use in wheel blasting systems and should be used with wear-resistant protective devices.

In summary, GL steel grit is a well-balanced abrasive, ideal for industrial surface treatment tasks that require medium hardness and durability.
