Junda steel shot and grit
Round steel shot have a uniform structure, optimal elasticity and high durability. Round cuttings are the ideal material for use in automatic installations for blasting turbines. Through its high impact strength and carefully controlled hardness steel cuttings provide maximum efficiency during blasting, leading to cost reduction.
The steel grit have a hardness similar to the steel shot, and their use is recommended for applications in removing slag and oxides of avtomatichnte installations for blasting. Repeat use the shots change shape having rounded.
Steel grit have an average hardness. Although hardness is higher than that of the spherical cuttings, they lose its angular shape at the time of blasting, but to a lesser extent. Their use is recommended for applications blasting using pneumatic systems.
The steel grit have the greatest rigidity and have the advantage to retain its angular shape after repeated use. This type of cuttings are ideal for abrasive blasting processes using pneumatic systems as performed even and rough handling. Also, their use leads to an increased efficiency of the blasting (m² / unit time).
Steel shot lighter than cast iron shot, the hardness is lower, 740 Knopp, resistance to erosion is higher therefore less dust, and a higher Cycle number. The cutting edges are resistant and result in homogeneous, high quality work.
Advantages: good resistance of the media to shock, sharp edges, more durable grains,lower consumption.The disadvantages are the same as for hematite cast iron, risk of oxidation of the grains trapped in the parts, and risk of mechanical obstruction due to stray shot.
Abrasive disposable. For cleaning operations, decontamination of stainless steel, the effect produced by the impact of the balls on the surface strips and sweeps the dirt leaving a satin finish. This technique is sometimes used to create effects with masking.
