Chilled Iron Grit G18

Understanding Chilled Iron Grit G18

Chilled iron grit is produced by crushing high-carbon iron shot into angular particles. The G18 designation refers to a specific particle size distribution within industry standards, typically corresponding to a coarse grade that balances high impact energy with a controlled profile. This hardness and angularity make it exceptionally effective for rapid stock removal and profiling on ferrous surfaces.

Unlike round shot, which peens and cleans, angular grit cuts and etches. The G18 grade is a workhorse in open-air sandblasting, wheel blasting machines, and blast rooms where heavy corrosion or thick coatings must be stripped quickly. It is commonly used before applying industrial paints, epoxies, zinc-rich primers, and thermal spray coatings.

Performance and Process Compatibility

Chilled Iron Grit G18 is compatible with both air-powered suction and pressure blast systems, as well as centrifugal wheel blast machines. Its high bulk density ensures efficient energy transfer, while the controlled particle size distribution minimizes nozzle clogging and provides uniform coverage. Users can expect a sharp, angular profile that promotes excellent coating adhesion.

While highly effective, this abrasive is best suited for ferrous substrates. It should not be used on stainless steel or non-ferrous metals where iron contamination could cause corrosion. For those applications, alternative non-metallic or stainless media are recommended. SPA2Z can advise on the right media for your specific substrate.
