Steel Shot

Premium‑Grade Steel Shot for Industrial Surface Treatment – High‑Durability Abrasive Media with Over 3,000 Recycling Cycles

Botou Junda Machinery Equipment Co., Ltd. manufactures high‑performance Steel Shot engineered for demanding industrial applications. Drawing on more than 20 years of foundry‑machinery expertise and our 3,000 m² production facility, we supply abrasive media delivering 3,000‑5,000 impact cycles per particle. Our blasting shot features hardness ranging from HRC 40‑50 (high‑hardness option up to HRC 55‑62), with consumption rate as low as 0.1‑0.3 kg per square meter. Our cast shot complies with SAE J444 standards, combining moderate hardness and excellent impact performance to optimise your blasting operations while lowering replacement frequency and overall production costs.

What Makes Our Steel Shot Ideal for Your Operations

Compared with conventional abrasives, our shot delivers superior metallographic density and toughness. The spherical design maintains stable kinetic energy upon impact, guaranteeing consistent rust‑removal efficiency and precise surface texture across all metallic workpieces.

Your production requires reliable abrasive media that does not fracture prematurely. The fatigue‑resistant composition of our material enables repeated cyclic blasting while minimising breakage, directly cutting your consumable expenses.

Uniform particle geometry simplifies downstream processes. Intact particles can be easily separated from broken ones using standard air‑separation and screening equipment, forming a true closed‑loop recycling system that maximises media utilisation.

Four Core Advantages to Reduce Operating Costs

Moderate Hardness with Excellent Impact Performance

Dense metallographic structure resists fragmentation under high‑velocity impact. This durability ensures stable energy transfer and consistent cleaning results across thousands of cycles.

Full Range of Available Particle Sizes

Twelve standard size grades ensure compatibility with hook‑type shot‑blasting machines, tumble‑belt shot‑blasting machines, rotary‑table systems and compact equipment. Whether you require light rust removal or aggressive oxide elimination, you will find the exact specification matching your target surface roughness.

Extended Recycling Service Life

High fatigue resistance brings lower breakage rates during operation. You will replace abrasive media less frequently, shortening procurement cycles and inventory costs while maintaining throughput.

Convenient Screening & Recovery

Uniform spherical geometry enables efficient separation by air classifiers and vibrating screens. Broken particles are cleanly discharged from the system while intact particles remain in circulation, maximising your return on investment.

Our Steel Shot fulfils essential surface‑treatment requirements for power generation, metallurgy, chemical‑processing, mining and coating industries. Foundries rely on our media to remove sand residues and mill scale from engine blocks and gearbox housings.

Steel‑manufacturing facilities use our abrasives to prepare H‑beams, bridge components and structural assemblies for protective coating. Consistent surface profiles meet strict cleaning standards required for long‑term corrosion resistance in infrastructure projects.

Aerospace and precision‑manufacturing operations utilise controlled shot peening to generate compressive‑stress layers on turbine blades and landing‑gear parts, effectively extending fatigue life under high‑stress conditions.

Frequently Asked Questions

Q: How do I choose between the two abrasive types?

A: Select the spherical type for smooth surface finishes and extended cycle life. Choose the angular type when you require high‑roughness profiles or aggressive removal of heavy oxide layers and weld beads.

Q: What is the normal abrasive consumption per square meter?

A: For light‑rust conditions, typical consumption ranges from 0.1 to 0.3 kg/m². Slightly higher consumption should be expected when treating thick oxide layers or heavily corroded surfaces.

Q: Does batch replacement of the spherical abrasive require regular maintenance?

A: Full replacement is not necessary. Conduct periodic screening to remove broken particles while continuously adding fresh media. Clean separator waste collection units every three to six months to preserve system efficiency.

Q: Can standard cast spherical abrasive be used for aluminium‑alloy parts?

A: We do not recommend standard carbon shot for aluminium workpieces. Iron contamination may cause surface darkening. Use stainless‑steel media to avoid galvanic issues and preserve surface integrity.
