4″*5/8″inch 100*16mm Blue ZA Fiber Disc for INOX
Product Overview
Designed specifically for stainless steel INOX surface refinement, this Blue Zirconia-Alumina Fiber Disc combines 85% ZrO₂ Zirconia abrasives with thermal-stable phenolic resin bonds. The round-center design delivers 30% higher contact pressure uniformity compared to standard discs, achieving Ra 0.4-1.2μm finishes on 304/316L grades.
Product Advantages
1.Anti-Clogging Matrix: Open-web abrasive distribution reduces loading by 55% during wet/dry operations.
2.Phase-Stabilized Grains: Maintain cutting efficiency from -15°C to 350°C operating temperatures.
3.Corrosion Resistance: Chromium-free formulation meets EU REACH standards for food-grade applications.
Applications
1.Metal Surface Preparation: Used for rust removal, paint stripping, deburring, and weld seam grinding on metal materials like structural steel and high-strength alloys.
2.Surface preparation of commercial kitchen equipment.
3.Final polishing on marine-grade stainless railings.
