Steel shot is spherical grains made of molten steel through an atomization (granulation) process, available in different sizes and hardnesses. It is used in airless wheel blast machines to clean foundry castings, surface polishing and shot peening.
Packed in 25kg bags
Special, stainless steel shot and high hardness specification shots available
Manufactured hypereutectoid steel abrasive
Grey, metal spheres
Used in airless wheel blast machines to clean foundry castings, surface polishing and shot peening
Also used in portable trackblast airless wheel blast machines for concrete floor preparation and profiling
Very long lasting
Can be recycled many times
