Metal abrasives are a common industrial material widely used for cleaning rust, oxide layers, and old coatings from metal surfaces, as well as for removing burrs and irregular edges to ensure the precision and safety of workpieces. Common metal abrasives include steel grit, steel shot, steel ball.
Yafeite Group has become a large-scale company integrating R&D, production, processing, sales, and international trade. It has a global market layout and its products are sold to more than 50 countries and regions in Europe, America, Africa, Australia, and Southeast Asia.
Many domestic industry giants and Fortune 500 companies have established strategic partnerships and continue to provide high-quality products, technologies and services to global customers.
Metal abrasives can quickly and effectively remove rust, oxide layers, and old coatings from metal surfaces, greatly improving work efficiency.
Due to their high hardness and wear resistance, metal abrasives have a long service life and can be reused multiple times, reducing costs.
During the cleaning process, metal abrasives can remove burrs and irregular edges, making the workpiece surface smoother and more even, thus improving surface quality.
Metal abrasives are suitable for various metal materials and different types of workpieces, making them highly versatile.
Metal abrasives are often recyclable, reducing waste generation and contributing to environmental protection.
By removing irregular parts and impurities from the workpiece surface, metal abrasives can improve the precision and safety of the workpiece, reducing potential safety hazards.
Steel grit blasting is an extremely popular abrasive used in
sandblasting operations, where it serves to clean surfaces prior to
coating, remove rust and paint deposits from steel surfaces, and perform
metalworking tasks such as scraping. Steel grit is valued for its
hardness, durability, and ability to be recycled multiple times without
losing effectiveness.

Surface Cleaning
Steel grit is widely used to clean and prepare surfaces, such as metal ones, to remove contaminants such as rust, scale, old paint or other pollutants. Due to its angular shape and hardness, it allows it to effectively create the necessary surface profile required for coating and adhesion purposes.
Shipbuilding and Maritime Industries
Steel grit is used extensively within the shipbuilding industry to remove marine growth, rust, and coatings effectively and ensure adhesion of protective coatings.
Deburring and Deflashing
Steel grit’s grinding properties make it ideal for deburring and deflashing applications, which remove burrs, sharp edges, or excess materials on metal parts – thus improving both their quality and functionality.
Foundry Applications
Within the foundry industry, steel grit is widely utilized to clean and descale castings, prepare surfaces for coatings and enhance finishes on metal parts – helping ensure consistent and uniform surfaces on cast metal parts.
Shot Blasting
The steel shot is powered by the high-speed rotating impeller on the shot blasting machine. The high-speed running steel shot continuously strikes the working surface, producing a force that separates the dirt (oxide skin, sand, etc.) on the surface of the workpiece from the workpiece itself, playing a cleaning role and making the appearance of the product uniform and beautiful.
Shot Peening
Using high-speed shot steel to impact the surface of the workpiece at room temperature, the surface material of the workpiece undergoes elastic-plastic deformation at recrystallization temperature, presenting an ideal microstructure and residual stress distribution, thereby improving the strength and fatigue resistance of the workpiece.
Cleaning and Polishing
Used in tumbling and vibratory finishing machines to clean, deburr, and polish metal parts to achieve a smooth and polished surface on metal components.
Surface Preparation
By utilizing the function of the impeller to compress air, steel shot and steel sand are sprayed onto the metal surface. While cleaning the surface, good roughness is produced on the metal surface, ensuring effective bonding between the coating and the metal surface during the spraying process.
