Introduction
Double quenched cast steel shot has higher hardness and can effectively increase its service life, with a much lower breakage rate than ordinary cast steel shot. The appearance presents a dark blue color, with better impact resistance performance.

Key Advantages
1. High cutting force: Double quenched grain refinement, high surface hardness, rust and oxide removal efficiency increased by 35% compared to ordinary steel shot, and thick rust and stubborn oxide are quickly removed.
2. Wear and tear resistance: The cycle life is 1800-2400 times, and the crushing rate is much lower than that of ordinary one-time quenched steel shot.
3. Stable roughness: hard spherical impact, high and uniform roughness of the workpiece, suitable for weight and anti-corrosion coating.
4. Low dust, reducing the wear of the impeller and protective plate of the shot blasting machine.
Applicable industries (Focusing on heavy rust removal)
Pre treatment line for steel plates, rust removal of thick steel plates for ships, sand removal for heavy castings, cleaning of thick oxide scale forged parts, rust removal for large steel structures, and peeling off of heavy paint surfaces for construction machinery.
