White aluminum oxide is an excellent abrasive choice for blasting stainless steel due to its hardness, sharp edges, and minimal contamination risk.
Why White Aluminum Oxide for Stainless Steel Blasting?
High Purity (99.5% Al₂O₃) – Leaves no embedded iron or silica contamination, critical for stainless steel to prevent rust or corrosion.
Sharp & Durable – Cuts efficiently without breaking down too quickly, making it cost-effective for repeated use.
Consistent Finish – Produces a uniform, matte surface ideal for welding, coating, or aesthetic finishes.
Recyclable – Can be reused multiple times in blast cabinets or suction systems.
Recommended Grit Sizes
#80–#120 – For aggressive stripping or heavy mill scale removal.
#150–#220 – For general cleaning and weld prep (most common).
#320+ – For fine finishing or decorative satin finishes.
Best Practices for Blasting Stainless Steel
Media Must Be Clean – Avoid cross-contamination from carbon steel blasting media.
Low Pressure (40–80 PSI) – Prevents peening or surface distortion.
Use a Dedicated Blaster – Never use equipment previously used on carbon steel.
