Stainless Steel Shot | AISI 410 (hardenable, 35-45 HRC) / AISI 430 (corrosion-resistant) spherical abrasive, AMS 2431/MI
1 / 7Stainless Steel Shot | AISI 410 (hardenable, 35-45 HRC) / AISI 430 (corrosion-resistant) spherical abrasive, AMS 2431/MIL-S-13165 compliant. Zero carbon contamination risk. For aerospace, medical equipment & food processing. 0.2-2.0mm, annual capacity 60,000 tons.
Manufactured from high-quality stainless steel, our stainless shot is ideal for applications where carbon contamination must be avoided. AISI 410 can be heat-treated to 35-45 HRC for shot peening and surface cleaning; AISI 430 ferritic stainless offers superior corrosion resistance for applications where hardness is less critical. Perfect for aerospace, medical equipment, and food processing industries. The stainless steel composition ensures zero iron residue on treated surfaces, eliminating the need for additional passivation steps.
After primary centrifugal quenching, we apply a second hardening cycle. This creates a denser microstructure, significantly inhibiting carbon deviation. The result: 1.3× longer service life, lower breakage rate, less dust, better elasticity and faster cleaning speed.
8-step controlled production — from raw steel to finished abrasive media, every stage is engineered for consistency.
Electric Arc Furnace
Adjust steel composition to reduce harmful sulfur and phosphorus content.
Ladle Refining
Further purify molten steel to ensure superior material quality.
Centrifugal Casting
High-speed centrifugal forming controls shape quality and minimizes physical defects.
Defect Separation
Remove hollow or deformed particles to improve shot density and uniformity.
Secondary Hardening
Double quenching refines grain structure, enhancing toughness and inhibiting carbon deviation.
Precision Heat Treatment
Precise temperature and time control achieve optimal hardness uniformity across batches.
Grit Production
Unique crushing process improves grit fullness and angularity while minimizing internal cracks.
