Introduction
Double-tempered high-toughness cast steel shot undergoes two additional tempering processes compared to ordinary cast steel shot. Its spherical surface is light bluish-gray, and the particles exhibit good toughness and are not easily damaged. It can be recycled and reused multiple times.

Key Advantages
1. Ultra high toughness, extremely low breakage: Double tempering fully eliminates internal stress, optimizes tempered martensitic structure, has extremely strong fatigue impact resistance, with a breakage rate of less 2%, and a service life of 2500-3200 times.
2. Extremely Less dust: Long term shot blasting is not easy to pulverize, the workshop meets environmental standards, and reduces dust removal costs.
3. Non damaging workpiece: Moderate hardness, no bumps or dents will appear when throwing thin plates or precision parts, fine and uniform roughness, excellent coating adhesion.
4. Low conductivity and low chloride ions, the workpiece is not easily rusted after shot blasting, suitable for high-end pre-treatment of automobiles and precision hardware.
