Abrasion-resistant Steel Grit

Purchased from Shandong Haishan Industrial Technology, abrasion-resistant steel grit is a high-durability, low-consumption premium abrasive specially customized for 24-hour uninterrupted automatic blasting lines.

Different from ordinary cast steel grit, it is smelted with chromium and manganese wear-resistant alloy elements to upgrade basic wear resistance, and further processed by cryogenic tempering densification to optimize internal metallographic structure. Its hardness is upgraded to HRC50-58 with balanced hardness and toughness.

It effectively solves the common defects of ordinary steel grit such as easy edge blunting, high fracture rate and short recycling life. While retaining complete sharp cutting edges, it greatly improves anti-fatigue and anti-impact performance, maintaining stable cleaning efficiency for long-term high-load continuous assembly line operation.

Core Advantages

1. Superior wear resistance and doubled service life

Its recycling lifespan is more than twice that of ordinary cast steel grit, with the fracture rate reduced by 60%, greatly lowering overall abrasive consumption for long-term production.

2. Long-lasting sharp edges ensure stable cleaning quality

The particles are not easy to round or passivate during long-term high-frequency operation, maintaining consistent and powerful cutting performance to ensure uniform workpiece treatment effect.

3. Less refilling reduces operation and maintenance costs

Ultra-low wear loss minimizes material replenishment frequency, saving labor costs and avoiding equipment downtime caused by frequent refilling, ensuring high-speed continuous production.

4. Ultra-low dust emission creates a cleaner workshop environment

The compact and tough particle structure hardly produces fine dust during operation, reducing workshop dust and lowering the load on dust removal equipment.

5. Reduced equipment wear extends service life of vulnerable parts

It alleviates friction loss of shot blasting machine blades, guard plates and other wearing parts, cutting equipment maintenance costs and prolonging overall equipment service life.

Product Disadvantage: Adopting high-grade alloy process, it has a higher unit procurement price. It shows outstanding cost performance in long-term continuous mass production, but is not suitable for intermittent construction, small-batch processing and temporary outdoor derusting scenarios.

Application Scope

This product is exclusively applicable to 24-hour unmanned, high-tempo and non-stop automatic shot blasting and sandblasting production lines, specialized in long-term low-consumption continuous industrial processing.

Main application scenarios: continuous through-type shot blasting lines for steel structures; full-automatic unmanned sand cleaning lines for castings; continuous anti-corrosion pretreatment lines for steel pipes; automatic batch sandblasting workshops for mass hardware workpieces.

Working Condition Positioning: Designed for high-load unmanned automatic assembly lines and long-term continuous mass production. It is not applicable for intermittent start-stop operation, small-batch scattered processing and temporary construction scenarios.

Frequently Asked Questions

Q: What is steel grit mainly used for? Which machines are suitable for using it?

Steel grit is mainly used for industrial rust removal, sand cleaning of castings, descaling, and surface matte treatment. Compatible with all conventional shot blasting machines, through-feed shot blasting equipment, and open-type sandblasting machines. It is highly versatile and can be used universally in steel structure factories, foundries, shipyards, and auto parts factories.

Q: How should one choose between steel grit and steel shot? What is the simple difference between them?

For rapid rust removal, sand cleaning, and thick oxide scale removal, steel grit (with sharp edges and high cutting force) is recommended. For surface polishing, strengthening, and fine sandblasting effects, steel shot (round, stable striking force, no damage to the surface) is recommended. For industrial heavy cleaning, steel grit is preferred.

Q: Can you provide steel grit samples for testing? How much do you charge for the samples, and how are they packaged?

We support free sample testing, with customers only responsible for the shipping costs. Samples are sealed in individual moisture-proof small packaging, with clear specification labeling, classified and individually packaged, without mixing or contamination, accompanied by a product parameter table and test sample data, to facilitate customers' actual testing on the machine. After comparing the quality inspection, place bulk orders if satisfied.

Q: What is the minimum order quantity for steel grit? Do you support small-batch trial orders for export?

Support small batch trial orders, LCL exports, and full container loads for bulk shipments, with no strict minimum order quantity threshold. For new customers and trial customers in foreign trade, we can flexibly adapt to small order requirements, assist customers in stabilizing the testing market and accumulating supply chain resources, and enjoy tiered discounts and exclusive shipping solutions from long-term cooperation.

Q: Is the steel grit packed in ton bags suitable for port lifting and automation equipment?

Fully compatible. Our 1-ton container bags are made of industrial-grade thick and wear-resistant material, paired with high-strength lifting straps, ensuring stable load-bearing performance that meets port lifting and forklift transfer standards. The packaging is neat and evenly stressed, allowing direct compatibility with factory automated feeding equipment and storage silo feeding, eliminating the need for secondary unpacking and repackaging. This significantly saves customers' loading and unloading, labor, and storage costs, making it suitable for bulk purchases by large enterprises.

Q: What is the core difference between domestic packaging and export packaging?

The core difference lies in the level of protection and compliance standards. Domestic packaging provides basic double-layer protection, meeting the needs of short-distance land transportation and regular warehousing. Export packaging, on the other hand, features a triple-layer structure that is thickened for waterproofing, moisture resistance, and salt spray resistance. It also incorporates desiccants, overall reinforcement, IPPC-compliant fumigation trays, and fully English international markings. Specifically designed for ocean shipping, cross-border quarantine inspections, and complex long-distance transportation scenarios, it offers comprehensive upgrades in protection, compliance, and stability, specifically addressing various risks associated with overseas transportation.

Q: How long does it take to replace steel grit after use?

There is no need for frequent batch replacement. Under normal use, steel grit becomes smaller and rounder due to repeated wear and tear, leading to a decrease in cleaning efficiency. It is only necessary to regularly replenish new grit and screen out dust and debris. This significantly reduces replacement costs, and only when there is excessive dust or a large amount of particle breakage does it require complete replacement.

Q: How much steel grit should be added for the first use of new equipment?

For the initial feeding of a conventional small shot blasting machine, it is sufficient to add 80% of the equipment's standard capacity, without filling it to overflow. Subsequently, based on the cleaning effect and sand output, add in small amounts but multiple times. Our factory can provide a customized feeding reference plan according to the customer's equipment model.
