Steel shot is spherical shape abrasive medium made from thermal-treated steel. Steel shots have fine and smooth micro-structure. That ensures high quality, durability and optimal cleaning properties.
Application:
Typical application areas: metal surfaces preparation before painting; descaling and rust removal; cleaning of steel profiles, rods or pipes; improving the stress-resistance of metal surfaces.
Advantages:
· Ideal to use for cleaning and polishing metal surfaces.
· Used to provide additional strength to the metal products being processed (crankshafts, engine turbine blades and high-power springs).
· Steel shots are used in both turbine and compressed air blasting systems.
· Due to its hardness and density, shots can be reused for up to 2700 times.
· Steel shots characterized by very low dust emission during the cleaning process.
