CAST-SUS304-05
Products Description
This product is a high-grade metallic abrasive manufactured through the melting, atomization, and cooling process . The raw SUS304 stainless steel is molten and then dispersed by high-pressure gas or liquid, forming fine spherical droplets that solidify into uniformly round shots . It is primarily used for surface treatment processes such as shot peening, blast cleaning, and descaling.

characteristics of 0.5 mM CAST-SUS304:
Spherical Uniformity: Smooth, round shape with no sharp edges, preventing surface damage and ensuring efficient material removal.
Low Breakage Rate: Heat-treated and quenched for structural integrity, reducing dust and abrasive waste to lower operational costs.
Corrosion Resistance: Optional stainless steel grade (304/316) or zinc plating for use in humid/caustic environments.

Advantage of 0.5 mM CAST-SUS304:
1.Exceptional Durability: Offers 3 to 5 times longer service life compared to conventional cast steel shot due to the high wear resistance of the dense stainless steel structure.
2.Superior Finish: Produces a uniform, clean, and contaminant-free satin/matte finish on metal surfaces, enhancing the base metal's appearance without embedding impurities or causing rust.
3.Consistent Performance: The spherical shape and tight size distribution ensure even peening coverage and predictable, repeatable results.

Usage
1.Shot Peening: Inducing compressive residual stresses to enhance the fatigue strength and resistance to stress corrosion cracking of critical components (e.g., aerospace parts, automotive springs, turbine blades).
2.Cleaning & Descaling: Effectively removing mill scale, oxides, welding slag, and old paint from stainless steel, aluminum, and other non-ferrous alloys without causing secondary rust.
3.Deburring & Deflashing: Smoothing edges and removing burrs from precision machined parts, castings, and forgings.
4.Decorative Finishing: Producing a uniform, high-quality satin or matte finish on consumer products, architectural metalwork (elevator panels, handrails), and kitchenware.

Applications
1.Surface Cleaning & Preparation: Removal of scale, oxides, and paints from stainless steel, aluminum, and other non-ferrous alloys.
2.Shot Peening: Inducing compressive stress to improve fatigue strength and resistance to stress corrosion cracking in critical components.
3.Decorative Finishing: Creating uniform matte or satin finishes on architectural metalwork, automotive trim, and household appliances.
4.Deburring & Deflashing: Smoothing edges on precision castings and machined parts.
