Steel Grit G25

　　Steel Grit G25 is an abrasive commonly used in sandblasting. It has high hardness and wear resistance and is suitable for cleaning, rust removal, surface strengthening and other processes. Here are some key information about Steel Grit G25:

　　1. Specifications and Characteristics

　　Grit Size: G25 indicates the particle size range of steel grit, usually between 0.7mm and 1.0mm.

　　Hardness: Usually 40-50 HRC (Rockwell hardness), with high wear resistance.

　　Shape: Steel grit is usually spherical or nearly spherical, suitable for recycling.

　　Material: High carbon steel or alloy steel, quenched and tempered to ensure hardness and toughness.

　　2. Application Areas

　　Surface Cleaning: Used to remove rust, scale, old coating, etc. on the metal surface.

　　Surface Strengthening: Improve the hardness and fatigue resistance of the metal surface through sandblasting.

　　Casting Cleaning: Clean the sand and burrs on the surface of the casting.

　　Pre-treatment for painting: provide a rough surface for painting or coating to enhance adhesion.

　　3. Advantages

　　Efficient cleaning: high hardness and fast cleaning speed.

　　Recyclable: strong durability and can be recycled many times.

　　Environmental protection: compared with other abrasives, steel grit can reduce dust pollution.

　　4. Precautions

　　Equipment wear: steel grit has high hardness and may cause certain wear to sandblasting equipment, requiring regular maintenance.

　　Cost: The initial cost is high, but recycling can reduce long-term costs.

　　Safety protection: protective equipment must be worn during operation to avoid damage from steel grit splashing.

　　5. Comparison with other abrasives

　　Steel grit vs. steel shot: steel grit is more suitable for cleaning rough surfaces, while steel shot is more suitable for surface strengthening and finishing.

　　Steel grit vs. quartz sand: steel grit is more environmentally friendly and recyclable, while quartz sand is prone to dust, which is harmful to the environment and health.
