Industrial Applications

Metal Fabrication

Pre-treatment of stainless steel components before welding, coating, or assembly processes. Creates optimal surface anchor patterns for subsequent treatments while removing mill scale and oxidation layers.

Abrasives Manufacturing

Primary raw material for bonded abrasive wheels, coated abrasive products, and loose abrasive compounds. Consistent particle size distribution ensures uniform product performance characteristics.

Tool Steel Preparation

Surface conditioning of high-carbon tool steels and die components. Medium polishing action removes machining marks while preserving dimensional accuracy and edge geometry.
