High-grade alloy steel shot with high density and less deficiency, the range of the grain size narrow. Special heat-treatment provides fine microstructure and optimum mechanical characteristics, which gives products the appropriate resilience and good fatigue resistance, and high cycling application rate and less consumption, this can increase the productivity and the profitability of your equipment. The steel shot can be applicable widely, like shot blasting for preparation of surfaces before coating for steel structures, reinforcement using pre-stressing or shot peening for mechanical components.
