Steel is one of the strongest and most dependable materials that can be used for blasting work. When it is made into steelshot abrasive blasting media or steel grit, it changes into a powerful way to clean, strip, and prepare metal surfaces. Both media are made from scrap steel that is melted, shaped, and hardened for use. The difference lies in the shape. Steel shot is round and smooth, while steel grit is sharp and angular.
What is Steel Shot and Steel Grit Abrasive Blasting Media?
Steelshot abrasive blasting media is round and designed for use in polishing and peening (strengthening) metal surfaces. Steel grit is quite angular and used when you are in need of a strong, cutting action. Both are heavy, long-lasting, and work best when used in the right equipment.
Benefits of Using Steel Shot and Steel Grit
The biggest benefit of steelshot abrasive blasting media is that this media can be reused many times before it wears out. Its high weight means each particle hits the surface with quite a strong force, making work faster and much more effective.
Steel shot gives a clean, smooth, sometimes shiny finish, but an added advantage is that it makes the metal stronger. Steel grit works faster when used in the removal of rust, paint, or thick coatings. Both come in different sizes and hardness levels, so you can match them according to your job.
How Does Steel Shot and Steel Grit Blasting Work?
In wheel blasting, a spinning wheel throws the media at quite high speed onto the surface. In air blasting, compressed air is used, but because steelshot abrasive blasting media is heavy, special or modified machines are often needed.
Steel shot works by gently peening the surface with many small, rounded impacts. Steel grit cuts into the surface to remove unwanted layers quickly.
Applications of Steel Shot and Steel Grit Blasting Media
Common uses for steelshot abrasive blasting media include:
- Cleaning and finishing auto parts
- Preparing steel before painting
- Cleaning castings in foundries
- Strengthening aerospace parts
- Restoring ships and heavy machinery
Steel grit is chosen when fast, deep cleaning or coating removal is needed.
Choosing the Right Steel Shot or Grit for Your Needs
When choosing steelshot abrasive blasting media, consider:
- Size: Small sizes polish better but cut slower. Large sizes strip faster but may leave a rougher finish.
- Hardness: Soft media is safer for delicate work. Harder media keep their shape longer for tough jobs.
- Equipment: Wheel blasting works very well with steel media. Air blasting can also work with the right setup.
Maintaining and Reusing Steel Shot and Steel Grit Abrasive
One of the reasons steelshot abrasive blasting media is cost-effective is its ability to be reused. If it is cleaned regularly and kept free from dust, it can last for many cycles. You should check it often—if grit becomes too round or shot gets too small, replace it for the best results.
Troubleshooting Common Problems in Steel Shot and Steel Grit Blasting
- Uneven results: The media may be worn out or the wrong size.
- Slow cleaning: Grit may have lost its sharp edges; replace it.
- Clogging: Check for moisture or dirt in the system.
- Too much dust: The media is breaking down, or the ventilation system is weak.
FAQs
- What’s the difference between steel shot and steel grit?
Steel shot is round and smooth for polishing and strengthening. Steel grit is sharp for fast cleaning and stripping.
- Can I reuse steelshot abrasive blasting media?
Yes, it can be reused many times if cleaned and stored well.
- Do I need special machines for steelshot abrasive blasting media?
Yes, because it is heavy, wheel blast systems or modified air blast setups are best.
