Description of Steel Grit
Steel grit is a very popular abrasive used in blasting operations for cleaning surfaces prior to coating, removing rust and paint deposits from steel surfaces, and performing metalworking tasks such as scraping. Steel grit is valued for its hardness, durability, and ability to be recycled multiple times without losing effectiveness.
Steel grit, commonly referred to as "steel grit," is an iron powder commonly used as an anti-slip agent in a variety of engineering projects. Made from high-carbon steel, steel grit forms particles with a sharp and angular structure when broken, making it particularly suitable for certain forms of sandblasting and surface treatment blasting techniques.

Steel grit applications
The most cost efficient blasting media in a closed system, where recycling is possible. Due to long extremely long life time, savings are made on abrasive cost itself, but also on disposal costs.
Surface Cleaning
Steel grit is widely used to clean and prepare surfaces, such as metal surfaces, to remove contaminants such as rust, scale, old paint or other contaminants. Due to its angular shape and hardness, it enables it to effectively create the necessary surface profiles required for coating and adhesion purposes.
Shipbuilding and Marine Industry
Steel grit is widely used in the shipbuilding industry to effectively remove marine growth, rust and coatings, and ensure the adhesion of protective coatings.
Deburring and Deburring
The abrasive properties of steel grit make it ideal for deburring and deburring applications to remove burrs, sharp edges or excess material from metal parts, thereby improving their quality and functionality.
Foundry Applications
In the foundry industry, steel grit is widely used to clean and descale castings, prepare surfaces for coatings and enhance the finish of metal parts, helping to ensure a consistent and uniform surface on cast metal parts.
Wheel Blast Machines
In shot blasting machines, mainly the softest steel grit GP is used (42-52 HRC). Steel grit GP is also referred to as angular shot, because it starts of angular but becomes round after some cycles in the wheel blast machine. When a more angular surface profile is required, steel grit GL (53-60 HRC) can also be used, for example when metallization follows after the blasting process. Not every wheel blast machine is suitable to work with the more aggressive GL hardness. Steel grit GH may never be used in wheel blast machines, because it will be brutal on the wear parts and inside of the machine.
In wheel blast machines steel grit is used for the removal of mill scale, rust, old coating layers on steel plates, steel beams and small steel parts. Steel grit is also used for deburring of metal parts and in the foundry industry the steel grit GP can be used for desanding of the foundry parts. Larger parts require a larger size abrasive.
Sometimes steel grit GP is added to work mix of shot to get some extra profile and aggressiveness to the blasting process.
Blast Cabinets
In pressure blast cabinets steel grit of GH hardness can be used, normally a finer grain size. Vacuum injection blast cabinets are not suitable, because the specific weight of steel grit is too high for this blasting method.
Vacuum Blasting Machines
In strong vacuum blasting machines like the AB1070, steel grit GH can be used. Normally the grain size GH40 or GH25 is suitable for this application.
