Bearing Steel Grit
Steel grit is produced by crushing steel shots. Steel grit has sharp edges therefore surface is cleaned much stronger and deeper compared to steel shots. Cleaning with steel grit also gives roughness to the surface. The properties of steel grits depend on the hardness of the metal. It is divided into GH, GL and GP types.
Application:
The most common applications are: preparation of metal surfaces before further coating, rust and old paint removing, surface profiling before rubber bonding, removal of contaminants from casting, and etc. Steel grit shots are perfect for strong and quick cleaning of metal surfaces. Used mainly with compressed air blasting equipment.
● Advantages:
With moderate hardness, high toughness, and impact resistance, this product can be used repeatedly several times, has a long lifespan, good rebound properties, strong adhesion, fast cleaning speed, low abrasive consumption, and does not break. It produces a high gloss finish on cleaned workpieces, achieving excellent technical results. Metal surfaces treated with this product achieve standard cleanliness. Surface roughness reaches 25-100µm, increasing the contact area on the metal surface, improving surface adhesion, and refining the metal surface while strengthening the metal structure.
