stainless steel grit blasting media
effect different from spherical stainless steel shot. It enables deeper micro-grooves on surfaces and
precisely meets technical requirements for high anchor profile depth.
Homogeneous Stable Composition, Free of Foreign Impurity Risks: Produced via integral smelting
without free iron contaminants. No iron embedding occurs on non-ferrous metals during long
continuous blasting, ensuring stable follow-up processes such as anodizing and passivation.
Wide Adaptability to Hot & Cold Working Conditions: Excellent temperature resistance prevents
discoloration under high or low temperatures. It resists rust and agglomeration in humid workshops,
featuring great storage stability and all-weather blasting adaptability.
Distinct Anchor Profile Suitable for Special Coating Systems: Generates well-defined peaks and valleys
on substrates.
- Product Description
Stainless Steel Grit Blasting Media – Premium Angular Abrasive for Contamination‑Free Surface Treatment
Botou Junda Machinery Co., Ltd. supplies professional‑grade stainless steel grit blasting media manufactured via precision melting and crushing processes. Our angular abrasives include SUS304 / SUS310 / SUS316 / SUS430 grades with controllable particle sizes ranging from 0.1 mm‑2.5 mm and hardness of 230‑600 HV, alongside a bulk density ≥7.5 g/cm³. Drawing on over 20 years of foundry‑machinery expertise and a 3,000‑square‑meter production facility, we deliver contamination‑free blasting solutions that eliminate iron‑embedding risks while achieving more than 1,000 recycling cycles. Our comprehensive R&D and manufacturing capabilities ensure consistent quality control to meet ISO11124‑4 standards for precision industrial applications.
What Makes Our Angular Abrasives Stand Out
stainless steel grit blasting media is produced by crushing hardened stainless steel into irregular polygonal particles with sharp cutting edges. Unlike spherical blasting media, this angular geometry removes material efficiently to form deep anchor profiles.
Compared with round media, the sharp‑edged structure delivers superior cutting performance. Each particle creates controlled micro‑grooves on treated surfaces, ideal for coating‑adhesion requirements. This design satisfies technical specifications for high‑roughness applications where surface etching is critical.
Our manufacturing process adopts integral melting technology with no free‑iron additives. It prevents metallic contamination during blasting operations on aluminum, copper, titanium and other non‑ferrous materials. Homogeneous composition guarantees stable downstream processes such as anodizing and passivation.

Performance Advantages You Can Rely On
Our angular abrasives perform excellently in high‑temperature‑resistant applications. The material maintains structural integrity under both high‑heat and cold working conditions without discoloration or performance degradation.
Moisture resistance prevents rusting and particle agglomeration in humid workshops. Your media remains free‑flowing during storage and delivers consistent blasting performance amid seasonal environmental changes.
The irregular particle structure creates well‑defined surface peaks and valleys. This anchor‑profile pattern dramatically improves mechanical interlocking with epoxy, polyurea, ceramic and special anti‑corrosion coatings used in high‑end equipment manufacturing.
Main Applications
Precision Manufacturing: Remove scale, burrs and oxide layers on stainless‑steel components without introducing iron contamination. Ideal for medical‑device finishing and food‑processing‑equipment preparation.
Aluminum Die‑casting: Effectively eliminate burrs from complex aluminum castings while preserving dimensional accuracy. The contamination‑free process avoids galvanic corrosion in assemblies combining multiple metal types.
Aerospace Components: Generate uniform matte finishes on titanium and special‑alloy parts. Controlled surface roughness meets strict coating‑adhesion standards for aerospace applications.
Architectural Stone Restoration: Powerful cleaning and texturing for granite and natural‑stone surfaces. Stain‑free properties prevent yellowing commonly caused by iron‑based abrasives in outdoor environments.

Frequently Asked Questions
Q: What is stainless steel grit and what are its shape characteristics?
A: Stainless steel grit is an angular abrasive manufactured by crushing stainless‑steel material with sharp cutting edges. Unlike spherical stainless‑steel shot, it removes surface contaminants through cutting action rather than peening.
Q: What workpieces are suitable for media?
A: Widely applied to stainless‑steel parts, aluminum die‑castings, copper products and precision non‑ferrous components. It removes scale, burrs and stains while producing matte surfaces with high roughness and zero iron contamination.
Q: How do I choose between stainless steel grit and stainless steel shot?
A: Select grit for heavy‑duty cleaning and building high‑roughness coating substrates. Choose spherical shot for matting, stress peening and applications where workpiece scratching must be minimized.
Q: How can I extend the service life of media?
A: Equip abrasive recovery and screening systems to separate fine powder and heavily fractured particles in a timely manner. Reasonably adjust blasting pressure, adopt wear‑resistant hoses and appropriate chamber‑liner thickness to reduce consumption.
Q: Can your media prevent rust spots on sensitive materials?
A: Yes. Our integral melting process eliminates free‑iron contaminants. For optimal results, use dedicated blasting equipment to avoid cross‑contamination from carbon‑steel operations.
