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.
