Steel shot ABRASHOT

Broken steel shot is a high-hardness product used, among other things, to remove old protective coatings. However, this is not its only use. It can also be used to improve the adhesion (roughness) of metal surfaces before painting, or to clean steel and iron castings.

High-Carbon Broken Cast Steel Shot

High-carbon broken cast steel shot is produced by crushing high-quality round cast steel shot in accordance with ISO 11125-1. The angular grain shape ensures aggressive cutting action and efficient surface preparation in blasting applications.

Hardness Grades (according to ISO 11125-3)

We offer broken cast steel shot in three standard hardness levels:

GP: 450 – 550 HV ± 40 HV (45 – 52 ± 2 HRC)
GL: 600 – 700 HV ± 45 HV (54 – 59 ± 2 HRC)
GH: 800 – 950 HV ± 60 HV (64 – 68 ± 3 HRC)

Each grade is designed for specific blasting intensity and surface treatment requirements.

Chemical Composition

The chemical composition corresponds to high-carbon round cast steel shot in accordance with ISO 11125-1.

Grain Size Range

Broken shot grain sizes according to distribution:

G 10 – G 325
in compliance with SAE J444 (AUG 84, revised May 1993).

Applications

Sharp-edged broken cast steel shot is mainly used for pneumatic abrasive blasting in blasting chambers and cabinets to:

Clean surfaces from rust, scale, contamination, and degraded coatings
Roughen surfaces to improve adhesion of protective coatings
Unify surface appearance
Remove burrs and sprues
Remove carbon deposits from heat-treated GL castings
