Advantages of Steel Grit Abrasive
Reduces Ineffective Cleaning
The angular shape of steel grit exerts a cutting action on metal surfaces, effectively removing mill scale, rust, and layers of old coatings. For heavy-duty steel structures, selecting the appropriate particle size enhances the efficiency of each cleaning pass, minimizing the need for rework caused by using the wrong abrasive specification.
Selection Based on End-Use Requirements
Larger particle sizes are suitable for heavy-duty surface cleaning, while finer sizes are ideal for precision treatment. When preparing steel for subsequent coating, both the coating specifications and the target surface roughness must be taken into account.
Focus on Controlling Breakage and Fines
At Hengtium, we prioritize long-term operational costs. We conduct continuous production testing-monitoring abrasive replenishment rates, cleaning performance, and dust collection system loads-to compare the actual usage costs of different abrasive specifications.
Hardness Selection Based on Operating Conditions
Steel grit abrasives are categorized into hardness grades: GP, GL, and GH. Typical reference ranges are approximately 40–51 HRC for GP, 54–61 HRC for GL, and generally 60 HRC or higher for GH; however, specific standards and supplier-defined metrics may vary.
The above provides an approximate reference range for common steel grit particle sizes; it does not represent the actual screening ranges for all Hengtium product models. Specific dimensions should be verified in accordance with applicable standards and the technical requirements of the order.
The data provided above is intended solely for preliminary selection purposes; actual hardness values should be verified against the supplier's technical documentation, applicable standards, and test reports.
For the cleaning of heavy-duty steel structures, it is advisable to evaluate both cleaning speed and abrasive consumption.
For automated production lines operating continuously, priority should be given to the consistency of product batches and performance during repeated use.
Applications of Steel Grit Abrasives
Steel Plate Processing and Structural Steel Fabrication
When placing an order, specify the initial level of corrosion, the intended coating system, and the required surface roughness to ensure the selection of an appropriate steel grit size.
Casting Cleaning
For castings with complex geometries, thin walls, or stringent surface finish requirements, verify the steel grit specifications and equipment parameters beforehand to prevent excessive impact.
Automated Sandblasting and Shot Blasting Lines
Regularly inspect the operating abrasive mix, the separator, and the dust collection system to minimize fluctuations in cleaning performance caused by changes in the condition of the abrasive mix.
Parameters to confirm before purchase
Note: The above are examples of common industry specifications. Please confirm the specific supply grade, chemical composition, hardness range, and packaging method with Hengtium.
Product Manufacturing and Quality Control
The chemical composition of the steel and the heat treatment parameters influence the hardness, microstructure, and fracture resistance of steel grit abrasives. Hengtium can specify product grades, applicable standards, and hardness ranges, and verify test results against project requirements.
Steel grit is produced by crushing steel shot into angular particles, which are then screened to achieve specific particle size grades. The quality of the screening process determines whether the steel grit meets the designated specifications. For bulk procurement, it is advisable to review the particle size analysis report and the permissible tolerances for screening.
Specific testing equipment, inspection frequency, and report types are subject to what Hengtium can actually provide. For long-term purchase orders, acceptance criteria and requirements for batch-specific documentation can be agreed upon in advance.
