What is GH Steel Girt?

GH Steel Grit is a high-hardness cast steel abrasive designed for aggressive surface treatment and cleaning applications. It is known for its durability, high impact resistance, and ability to maintain its angular shape during use, making it highly effective for heavy-duty tasks.

Characteristics

1.Hardness: GH steel grit has a hardness range of 60-64 HRC, making it the hardest type of steel grit available.

2.Shape: It maintains its angular shape even after multiple recycling processes, ensuring consistent and aggressive cleaning.

3.Chemical Composition:

(1) Carbon (C): 0.80-1.20%

(2) Manganese (Mn): 0.35-1.20%

(3) Silicon (Si): 0.40-1.50%

(4) Sulfur (S): ≤0.05%

(5) Phosphorus (P): ≤0.05%

(6) Density: Approximately 7.6 g/cm3.

(7) Bulk Density: Around 4.2 kg/l.

Applications

GH steel grit is ideal for:

1.Deep Descaling: Effective in removing heavy oxide scale from large steel products.

2.Surface Preparation: Creating deep anchor profiles for coatings, rubber bonding, and lining.

3.Blast Cleaning: Removing old coatings, rust, and mill scale from steel surfaces.

4.Shot Peening: Enhancing fatigue resistance by inducing compressive stresses on metal surfaces.

Usage Considerations

1.Equipment Compatibility: GH steel grit is primarily used in compressed air blast systems due to its high hardness. It is not recommended for wheel blast machines unless they are specifically designed to handle such aggressive abrasives.

2.Recyclability: GH steel grit can be reused multiple times in closed systems, making it cost-effective.

3.Dust Generation: It produces minimal dust, improving visibility and reducing cleanup costs.

Available Sizes

GH steel grit is available in various grain sizes to suit different applications:

(1) GH12: 1.70 – 2.40 mm

(2) GH14: 1.40 – 2.00 mm

(3) GH16: 1.00 – 1.70 mm

(4) GH18: 0.70 – 1.40 mm

(5) GH25: 0.40 – 1.20 mm

(6) GH40: 0.30 – 1.00 mm

(7) GH50: 0.20 – 0.70 mm

(8) GH80: 0.10 – 0.40 mm

(9) GH120: 0.10 – 0.30 mm

In summary, GH steel grit is a highly effective and durable abrasive for heavy-duty surface treatment tasks. Its high hardness and ability to maintain an angular shape make it ideal for deep descaling and aggressive cleaning applications.
