Steel grit is an abrasive material made from high-quality steel particles that are used for surface preparation, cleaning, and abrasive blasting applications. It is widely utilized in industries such as construction, manufacturing, shipbuilding, and foundries. Steel grit is distinct from steel shot in terms of shape and application.

Unlike steel shot, which has a spherical or rounded shape, steel grit is angular or shard-like in form. The manufacturing process involves crushing steel shot into smaller particles and then tempering them to achieve the desired hardness. This results in sharp-edged grits that are highly effective in removing tough coatings, rust, and scale from various surfaces.

what is steel grit

Steel grits are available in different sizes and hardness levels to suit different applications and surface conditions. The size of steel grits is typically measured using mesh or sieve sizes, ranging from fine grits (e.g., G18) to coarse grits (e.g., G80). Hardness levels are measured on the Rockwell C scale and are denoted by an alphabetic letter (e.g., GP, GL, GH), with higher letters indicating higher hardness.

The angular shape of steel grits allows for aggressive cutting and impact, making them ideal for applications that require intense surface cleaning or profiling. Some common uses of steel grit include removing heavy rust, scale, and coatings, as well as preparing surfaces for coatings or bonding.

Steel grits offer several advantages:

  • Cutting Power: The sharp edges of steel grits facilitate efficient cutting and removal of tough surface contaminants.
  • Surface Profile Control: Steel grits can create a rougher surface profile on substrates, which is beneficial for coatings adhesion and providing texture.
  • Durability: Steel grits are highly durable and can withstand multiple uses before they need to be replaced.
  • Recycling Potential: Similar to steel shot, steel grits can be recycled and reused, making them a sustainable choice that reduces waste and overall costs.

When selecting steel grits, it is important to consider factors such as the surface material, desired surface profile, and equipment being used to ensure optimal performance and safety.

In summary, steel grit is an angular abrasive material known for its cutting power and effectiveness in demanding surface preparation applications. Its unique shape and hardness make it a preferred choice for tasks that require aggressive cleaning, profiling, and coating adhesion.
