Cast Steel Grit - SG:
Cast steel grit uses high quality steel scrap as main raw materials and is produced through various working procedures. Secondary quenching and medium temperature tempering processes in cast products and ensure that the cast steel shot and grit have high strength, hardness and wear resistance.
Applications:
v Reusable abrasive
v Sand removal
v Descaling
v Micro and structural blasting
Blasting Systems:
v Pressure blast systems
v Airless blast-cleaning equipment
