1. Product Overview

Bearing steel grit is a high-end polyhedral angular metal abrasive. It is made of high-purity chromium bearing steel through sophisticated processes including precision quenching, crushing, tempering and graded screening.

Different from traditional abrasives such as ordinary cast steel grit and carbon steel grit, it features uniform metallographic structure, no shrinkage cavities and no porosity defects. As a high-performance core abrasive in industrial surface treatment, stone processing and mechanical strengthening, it is widely used in high-end manufacturing, heavy industry infrastructure, new energy, ship anticorrosion and other industrial fields, thanks to its extreme wear resistance and stable working performance.

2. Core Characteristics

2.1 Ultra-high Hardness & Powerful Cutting Capacity

Through professional heat treatment, the hardness of bearing steel grit stably reaches HRC60-65, with sharp and regular particle edges and strong penetrating power. It improves the efficiency of rust removal, oxide scale removal and coating residue removal by more than 30% compared with ordinary abrasives. It can quickly eliminate surface rust, oxide layers, oil stains and impurities of workpieces, meeting high-standard and high-precision surface cleaning requirements with a high qualification rate of workpiece surface cleanliness.

2.2 Excellent Toughness & Recyclable with Low Loss

Made of high-quality bearing steel, the product has high strength, impact resistance, fragmentation resistance and fatigue resistance. It is not easy to break and produces little dust during high-speed blasting operation.

Compared with traditional cast steel grit, the comprehensive loss is reduced by about 40%, and it can be recycled for many times. It effectively reduces enterprises’ abrasive procurement cost and on-site dust removal maintenance cost, achieving higher comprehensive cost performance.

2.3 Uniform Particle Size & Stable Treatment Effect

Adopting precision grading and screening technology, the product has standard and evenly distributed particle sizes with a density of 7.54g/cm³. The uniform force during operation forms standard and consistent anchor patterns on the workpiece surface, greatly improving the adhesion between anti-corrosion coatings/paints and metal substrates. It avoids coating peeling and blistering, and permanently guarantees the anti-corrosion effect of workpieces.

2.4 Stable Performance & Wide Working Condition Adaptability

With precisely controlled chemical composition and dense metallographic structure, bearing steel grit has outstanding high-temperature resistance, wear resistance and aging resistance. It is applicable to various working conditions such as dry blasting, wet blasting, shot peening strengthening and stone sawing. It delivers stable and standardized processing results for both heavy-duty workpieces and precision mechanical parts, not affected by ambient temperature and working intensity.

2.5 High Purity & No Secondary Pollution

After fine purification and impurity removal treatment, the product has no internal impurities, pores or loose defects. It will not cause scratches or residual pollution on the workpiece surface during operation. It fully meets the high-standard surface treatment requirements of high-precision equipment and export workpieces, supporting products to pass various industrial quality inspections.

3. Main Application Scenarios

3.1 Pretreatment for Steel Structure & Heavy Industry Anticorrosion

It is widely used in sandblasting rust removal and oxide scale removal for large heavy-duty components such as steel structure workshops, bridges, towers, construction machinery, mining machinery and port equipment. It thoroughly removes surface rust and rolling oxide scale of steel materials, forms a uniform anchor pattern base, and provides a firm foundation for heavy-duty anti-corrosion coatings and paint spraying, significantly improving the anti-corrosion life and operational stability of infrastructure equipment.

3.2 Ship & Offshore Engineering Equipment Treatment

It is suitable for surface pretreatment and renovation maintenance of ship steel plates, cabin structures, offshore platforms and port machinery. The substrate treated with bearing steel grit has stronger coating adhesion, which can effectively resist seawater erosion and sea wind oxidation, serving as an essential core abrasive for ship heavy-duty anti-corrosion projects.

3.3 New Energy & Pressure Vessel Manufacturing

Applied in shot blasting cleaning and stress relief for wind power towers, hydropower penstocks, photovoltaic brackets, pressure vessels and pipeline equipment. It removes surface impurities and improves surface smoothness, while eliminating residual internal stress of metal workpieces through shot peening strengthening, enhancing the fatigue resistance and ensuring long-term safe operation of new energy and pressure equipment.

3.4 High-end Stone Cutting & Processing

It is a special high-quality abrasive for sawing and processing hard stones such as granite and marble. Its sharp angular cutting structure greatly improves stone cutting efficiency by 30%-50% compared with ordinary abrasives. The processed stone has smooth cuts without edge chipping or cracks, effectively improving the qualification rate and processing precision of finished stone products for large-scale factory production.

3.5 Precision Machinery & Auto Parts Strengthening

Used for surface cleaning, deburring, oxide removal and surface strengthening of automobile chassis parts, mechanical castings, precision molds and hardware components. It accurately removes processing burrs and flashes, optimizes surface roughness, and improves surface hardness and wear resistance of parts to extend the service life of precision components.

3.6 Aviation & Rail Transit Supporting Processing

It meets the strict high-standard surface pretreatment requirements of aviation parts, locomotive vehicles and rail transit equipment. With the advantages of low dust, high cleanliness and no secondary pollution, it ensures the surface treatment precision and anti-corrosion grade of high-end equipment manufacturing.

4. Comprehensive Advantage Summary

Bearing steel grit makes up for the shortcomings of traditional abrasives such as high loss, poor effect, excessive dust and easy pollution. With the comprehensive advantages of high hardness, sharp cutting, low wear loss, uniform particle size, stable performance and high cleanliness, it is widely applicable to various industrial surface cleaning, strengthening and stone processing scenarios.

It helps enterprises reduce abrasive costs, improve processing efficiency and optimize product quality, serving as the preferred high-performance metal abrasive in modern high-end industrial manufacturing, heavy-duty anti-corrosion and precision processing fields.
